Samadhi

 are a mind, and you are a body. that is what you are, that is what you experience yourself as. You are, on the most fundamental level of reality, awareness. You are awareness the same way you are particles - atoms, protons, electrons, quarks. It is your most fundamental nature that you don’t experience, but that causes you to be self aware.

You are a self-aware body mind.

Samadhi is when the awareness that you are, fundamentally, expands to such an extent that you not only experience it directly, but you become it. In samadhi you are awareness experiencing itself directly.

This experience is analogous to suddenly experiencing your body as a cloud of quarks. I mean literally looking down on yourself and seeing particles swirling around where your body should be. This would be the equivalent of samadhi, when you experience directly what you are actually made of.

There is nothing you can do to achieve it. You, the mind, can’t do anything to make awareness expand like that. It doesn’t matter what the mind let’s go of or clings to. The mind doesn’t matter to samadhi at all. Samadhi is an event of awareness itself, and the mind has no influence over that.
