LUCID DTH STUDY
In addition to hearing the patients’ experiences, the researchers observed spikes in brain activity – specifically, in so-called gamma, delta, theta, alpha and beta waves.
In some cases, these activity spikes were observed when CPR had been going on for up to an hour.
“These recalled experiences and brain wave changes may be the first signs of the so-called near-death experience, and we have captured them for the first time in a large study,” says lead investigator Dr Sam Parnia, an intensive care physician and associate professor in the Department of Medicine at New York University Langone Health, US.
“Our results offer evidence that while on the brink of death and in a coma, people undergo a unique inner conscious experience, including awareness without distress.”

SANDILYA VIDYA
SWAMI KRISHNANDA
om āpyāyantu mamāṅgāni vāk prāṇaś cakśuḥ śrotram atho balam indriyāṇi ca sarvāṇi.
sarvaṁ brahmaupaniṣadam mā'haṁ brahma nirākuryāṁ mā mā brahma nirākarot anirākaraṇam astu anirākaraṇam me'stu.
tad ātmani nirate ya upaniṣatsu dharmās te mayi santu te mayi santu. Aum śāntiḥ śāntiḥ śāntiḥ. (Kena Invocation)
Sandilya, the great Rishi, had this revelation of the Supreme Being. Vidya is a meditation, an art of thinking on the Supreme goal. This meditation begins with the proclamation of the all-comprehensiveness of Brahman: “Sarvam khalvidam brahma – All this is verily Brahman.” This vidya is contained in Section 14 of Chapter Three of the Upanishad.
sarvaṁ khalvidaṁ brahma tajjalāniti śānta upāsīta | atha khalu kratumayaḥ puruṣo yathākraturasmipuruṣo bhavati tathetaḥ pretya bhavati sa kratuṁ kurvīta ||3.14.1||
This is a very famous passage in the Upanishad. This is how we have to meditate, calmly, quietly and peacefully. We have to meditate that everything comes from That, everything is sustained in That, and everything returns to That. That which is the origination, the sustenance and the dissolution of all things is this Brahman. Inasmuch as it is the cause of all things, naturally, every effect in the form of this creation is contained there. We too are effects of creation. So, we too are contained in it. There is a great justification in the assertion that everything is the Supreme Being. Logically and naturally, when the effects are all contained in the cause, one should be able to appreciate the all-comprehensiveness of the ultimate cause. This cause only is, inasmuch as no effect can be separated from the cause. There is an undifferentiated relationship between the effect and the cause. There is no gap between the one and the other. We are, therefore, not isolated from the cause. There is no vital cut or gulf between this universe of effect and its cause which is Brahman. This means to say that even now we are vitally connected with the Absolute. We are maintaining even at this moment an organic relationship. The difficult part of this meditation is that we ourselves, as thinkers, are associated vitally and organically with the Supreme Being on whom we have to meditate. We cannot think like this, for the mind refuses to think. We can think something outside us and we can think of the whole universe practically, but we cannot think something in which we ourselves are involved, because there it is that the mind finds itself incapable of functioning. There is no such thing as mind thinking itself.
Aristotle said that God is thought thinking itself. It is very difficult to understand what it means. How can thought think itself? It always thinks something else. So, Brahman cannot be thought by the mind, and yet this is the injunction of the Upanishad. The highest kind of meditation is sarvam khalvidam brahma. All this manifestation which you see in the form of individuality, whether organic or inorganic, visible or invisible, wherever it be, is That. Nothing but That is.
Again to reiterate, the most difficult thing to swallow here is that we ourselves are a part of That. The meditator is part of that which is meditated on. How is one to even think? It requires a tremendous psychological preparation and an extraordinary type of purity of mind to appreciate what this instruction is. This is not an ordinary type of meditation. It is most extraordinary in the sense that you are contemplating yourself, as it were, and not something or somebody else. That is implied in the statement that everything is included in That, not excluding oneself who meditates.
Thus should you meditate: “Sarvam khalvidam brahma – all this verily is the Supreme Absolute Brahman.” How do you contemplate Brahman? The whole universe – you can imagine what the universe could be – has come from That. It has not come from That as something different from That. The very substance of this creation is the substance of the Absolute. That is one aspect of the matter. The other aspect is that there is no disconnection between the effect and the cause. So you can imagine how hard it is to entertain this thought.Everything is That because of the effect being non-disassociated from the cause. It is connected with the cause. It is sustained, even now at the time of the apparent creation, in That only – and it will go back to That. So there is no place for anything to exist except That. Also, there is nothing other than That. Thus, one should meditate.
The word kratuhas several meanings. It means an effort of the will, an action of the mind, a determination of the understanding and a meditation that you practise. All this meaning is comprehended by the word kratu. The whole of one's life is nothing but a determination or willing in this manner. Throughout our life we will in some way or other. The individual is an embodiment of action performed through his will. And whatever we will, that we become, because of the intensity of the will. As we affirm, so we experience – and that we become. Our experiences are nothing but our affirmations through will. We have affirmed something very intensely in our previous lives, and the reward of those affirmations is the present series of experiences we are passing through here. So this is a caution, again administered to us. Inasmuch as whatever we think intensely and continuously, and that we are going to become, what should we think throughout our life if we want to become Brahman? We want to become the Absolute Itself. What should be the kind of thought that we should entertain? What should be the type of affirmation that we should make? How should our will work? This need not be explained further, because it is obvious. Therefore, my dear readers, spend your time in absorption of your thought in Brahman. This should be your meditation throughout your life. The Upanishad gives some further details as to how we should conduct this meditation in our life.
manomayaḥ prāṇaśarīro bhārūpaḥ satyasaṁkalpa ākāśātmā sarvakarmā sarvakāmaḥ sarvagandhaḥ sarvarasaḥ sarvamidamabhyatto'vākyanādaraḥ ||3.14.2||
The whole mental world is permeated by this Being. The light of the mind, the light of understanding, the light of intelligence, is the light of Brahman. It appears to be embodied through these pranas and the body. They are a vehicle, an embodiment to particularise this infinite consciousness. And as I have mentioned already, even these as effects are not different from consciousness, the cause. So, this mental body or vital body of ours is not to be regarded as distinct from the Absolute. They are only occasions for the meditation on Brahman. From the particular we have to go to the universal. Though the particular is limited in comparison with the expanse of the universal, qualitatively it cannot be different from the universal. Just as from a drop you can know the ocean, from the particular we can reach the universal. Thus is the meditation. It is effulgence in its nature and light is its character. It is the glory of consciousness that is effulgence.
Whatever is willed through this consciousness is materialised at once – satyasamkalpa. This is what we studied in the last chapter of this Upanishad.
The Self of this Being is as vast as space. It is not a limited individual self. The whole space itself is the Self – akasatma. As vast as space is, so wide is this Self which is Brahman. It is, therefore, all-comprehensive.
All actions are its actions – sarvakarma. It performs everything. Whatever I do, whatever you do, whatever anyone does, whatever happens anywhere in all the levels of creation – all these are activities of that Being. It is the fingers of God working through all these phenomena of nature. All the ways in which the mind thinks are the ways He thinks.
Sarvakarma – all the wishes in your mind, all the desires, are the desires of the Self ultimately in some way or other. Every kind of desire, whatever the nature of the desire be, is nothing but a movement of consciousness towards universality in some way or other. This subject is discussed in some detail in the Brihadaranyaka Upanishad, which describes how every desire is universal desire ultimately. Anything that you smell through the nose is again an activity of That Being only – sarvagandhah. This again has been mentioned earlier, in the last chapter of the Upanishad. The objects as well as the means of cognition are both Itself only appearing objectively on one side in one aspect, and subjectively in another. All the tastes, anything that you contact through the organ of taste, is nothing but Its activity – sarvarasah.
Everything is enveloped by That – sarvamidamabhyatto. What further can we speak of It? It is enveloping all – isavasyam idam sarvam as the Isavasya Upanishad puts it. Inside and outside It is there as the antaryamin. It does not speak, but It can convey Its message and It is free from agitation and eagerness – avaki adarah. It has no desires in the ordinary sense. It is not eager to grasp things, grab things and have things, because It is all things. This is not merely a teaching giving some information, but it is instruction about meditation, the way in which a mind has to be organised in daily meditation so that it may not wander from place to place and may not think of many things. The many things do not exist. What will the mind think when it knows this truth!
eṣa ma ātmāntarhṛdaye'ṇīyānvrīhervā yavādvā sarṣapādvā śyāmākādvā śyāmākataṇḍulādvaiṣa ma ātmāntarhṛdaye jyāyānpṛthivyā jyāyānantarikśājjyāyāndivo jyāyānebhyo lokebhyaḥ ||3.14.3||
This great Being, the Supreme Brahman is in one's own heart as fine and subtle as one can conceive of. It is the subtlest. It is most subtle even among those that we regard as very subtle in this world. Subtler than a grain of rice or paddy, subtler than a grain of millet, subtler than the kernel of this grain, so small, subtler than a mustard seed is this great Being who is seated in one's heart. But does it mean it is as small as a mustard seed? No, it is at the same time as vast as the whole of creation. So, objectively also it has to be contemplated, in the same way as we contemplate it subjectively as our own deepest Self inseparable from the whole cosmos. This little thing referred to as one's own Self here is bigger than this vast earth. It is not merely as fine as a millet seed, but also vaster than this whole earth and this entire atmosphere. It is vaster than all the worlds, not merely this one atmosphere. It is larger than even the sky and the heavens. It is vaster than all the fourteen worlds of creation which cannot comprehend its magnitude. So vast is its objectivity and magnitude, being infinite in its expanse, and yet it is in me, in you, and in every one of us, as if it is so little like a small flame of light!
This symbology is given only for the purpose of contemplation, because it has to be taught to us that it is not merely an infinite expanse outside us, unconnected with us as a transcendent something, but is identical with our own Being also. The Upanishads are never tired of hammering this idea into us – that the Supreme Being is both objectively infinite and subjectively the Self of everyone. This is the principal meditation of almost every part of any Upanishad. It is the vast infinitude, incomprehensible to the mind, and yet nothing can be so near to us as That. It is so distant as the distant horizons themselves because of its infinitude and vastness, and yet so near as to be well nigh inseparable from us because it is the Atman itself.
sarvakarmā sarvakāmaḥ sarvagandhaḥ sarvarasaḥ sarvamidamabhyātto'vākyanādara eṣa ma ātmāntarhṛdaya etadbrahmaitamitaḥ pretyābhisaṁbhavitāsmīti yasya syādaddhā na vicikitsāstīti ha smāha śāṇḍilyaḥ śāṇḍilyaḥ ||3.14.4||
Sandilya, who was a great sage, proclaims this great knowledge: “This great Being whose actions are all actions, whose desires are all desires, whose functions are all functions through the senses, is inside me and It is that which is inside everything.”
The reason why the Atman is called Brahman is because it is the Self of all. As the Self of each one, it is called the Atman. As the all-comprehensive Self, it is called Brahman. The doubt that may arise in the mind as to the localisation of the Atman is removed by the assertion that it is the Self of all. It is a contemplation on the all-pervading Self, the universal Self. Therefore, the Atman in one is the Brahman everywhere.
”This Brahman is what I am” – thus we should meditate. The moment we get up in the morning this thought should come to the mind. The progress of our life in spirituality can be judged from the first thought that occurs to the mind in the early morning when we get up. What is the first thought that comes to our mind the moment we wake up from sleep? That will give us an idea as to what we have been thinking throughout the day. The conscious mind remains suppressed and the impulses alone work in the deep sleep state, and these impulses will thrust up certain ideas the moment we get up. It may be something which is connected with this world or something which is related to our sadhana. It may be a thought of anxiety or it may be a thought of freedom. It may be a thought of anything, depending upon the thoughts during the waking state. From this we can have an idea, an inkling as to how we have been conducting our thoughts.
The Upanishad tells us that we have to meditate in this manner throughout the day. As much time as we can spare for this purpose, we must utilise. We have to grow gradually, stage by stage, to that state of Being, when we will be able to give all our time for meditation. Many a time we have difficulties in finding time for meditation, because of the vocations of life. So, in the earlier stages, the advice is that as much time as you can spare should be set apart for the purpose of meditation, even if it be only for half an hour or forty-five minutes, or even less than that because it is not easy for the mind of the neophyte to accept that everything that it thinks can somehow or other be reconciled with spirituality. It always regards the ordinary life of the body and the senses and social existence as different from spirituality. This is the habit of the mind, although it is not correct. This is what it believes. In the beginning, therefore, it is necessary to give some time to meditation – conveniently, of course, not with great effort and hardship on oneself. The life of the spirit is not one of suffocation or stifling of the mind. It is a gradual growth of the mind spontaneously, like the growth of a baby into an adult without any kind of stifling of functions. We should give as much time as is conveniently possible, with satisfaction to the mind. Then the time has to be increased by reduction of external activities, sleep, and the unnecessary things that we do in life which are not actually essential. You may be going to a club or to a picture, or you may be having a chat with some friends. All these can be gradually curtailed, because they are not essential. Essentials alone should be maintained. And still later on, in a more advanced stage, we must learn the art of seeing no distinction between our ordinary life and spiritual life. That is what is actually expected of us as spiritual seekers.
There is no such thing as an unspiritual life, finally. This has been told to us again and again in the Upanishad. Things look unspiritual on account of our peculiar way of evaluation. The idea of ‘I-ness' and ‘my-ness' is the cause of this peculiar notion in the mind, of there being a distinction between the ordinary life and spiritual life. We should not however do things which we regard as wholly unspiritual, or irreconcilable with our ultimate aim. We should not do also that which is wholly irrelevant to our life. We should not have any kind of despondency or diffidence in our heart that the most part of our life is spent in unnecessary work. There is always some connection between our work and the spiritual purpose that we are having in our mind. But the wisdom lies in understanding what this connection is. The connection is one of non-distinction. Though this connection is there, we are not able to keep its awareness. When this awareness arises we enter into a flood of an all-comprehensiveness of approach through every aspect of our life.
So meditation should be a continued practice. How long should we continue the meditation? We must continue until we attain Self-realisation or until we die, whichever is earlier. Whoever has such intense faith, as is mentioned here, shall get it. If we have intense faith, we will get it! You should not have a shaking mood of the mind. There should not be any doubt or suspicion. “Am I fit for it?” “Will I get it?” “What is the good of it?” – this kind of doubt should not arise in the mind. “I must get it.” “I am doing the best possible thing.” “I am putting forth all my effort to the extent of my possibility.” “I am doing my duty.” Such a doubtless attitude should be maintained throughout life. If one has faith of this kind, one should certainly attain it. There is no doubt about it. This is what the whole Upanishad is teaching, which is compressed in this vidya called Sandilya Vidya.Though it is very short, yet it contains everything.
The meaning of this vidya, meditation, is very profound. The more we think about it, the greater and deeper are the meanings that we will discover in it. And these meanings will be discovered as we go deeper and deeper into meditation. So here, we have got in the Sandilya Vidya the whole subject of the Upanishad clinched, as it were – kept inside our fist for the purpose of daily habituation of the mind to spirituality and God-awareness.
This vidya contains the art of adjusting the mind inwardly as well as outwardly in the beginning by alternate processes, and then finally grasping the comprehensiveness of Brahman, the Reality in its simultaneously dual aspect of universality and individuality.
Dādau brahmāhamasmītyanubhava udite khalvidah brahma pascat, is a passage from Acharya Sankara's ‘Satasloki' wherein he makes a reference to this vidya. He mentions how the consciousness rises gradually from the level of individual perspective to the universal one. It is not easy to understand the meaning of what Acharya Sankara is saying here because of the fact that we cannot distinguish between our personality or individuality and the Atman, to which reference is being made. We always mix up the two. The Atman is myself, and we know very well what we understand by the word ‘myself'. It is an inveterate habit of the mind to think in terms of the body. So, whatever be the thing that is associated with individuality is at once identified in meditation. The kernel that is within us, the essence that we are, is to be separated from the body that we appear to be in this technique of meditation. In the beginning, there is consciousness that one's own self is all. Now, this is not merely a statement that is to be studied grammatically or linguistically, but is a matter of experience. One's location in all things in addition to one's own body becomes a revealed truth in the advanced stages of this meditation. There are some examples to show how this happens.
It is something like the space within a vessel realising that it is everywhere. Just compare yourself to a little space that is contained in a small glass tumbler which has got obsessed with a notion that it is inside the glass tumbler only and that what is outside as space is not itself, but an object of itself – something external to itself. It has to elevate itself to the awareness of the non-distinguishability between itself and the external space. That is the real meaning perhaps of what is in the mind of Acharya Sankara. I am the all! The space within the vessel realises that it is all-space. It does not mean that it has become all-space by any effort of its imagination or activity. It is just a rising to the awareness that the wall around it, namely, the tumbler or the glass, is not going to limit its all-pervasive nature.
Then the realisation comes – khalvidah brahma pascat. It is not merely the ‘I' that has become all, but every one is the same all. The Self that is in me is not in me only. The assertion, “aham brahmasmi – I am Brahman” can be made by each centre of individuality in a similar manner. This is a larger realisation, says Sankara. It is a rise from the limitation of one's individuality upto the cosmic Reality of one's essence, with a simultaneous awareness of the identity of every self, the so-called multiplicity of selves, with this single Self. So it is the total of all the selves in an indistinguishable mass rising to a single comprehension of the great Absolute Brahman. This is the actual inner import of the meditation which is called Sandilya Vidya.
