NIETZSCHE X BK X ADVTA

 A

If by Kastrup you mean Bernardo Kastrup, here’s a compact comparison with Nietzsche and Advaita Vedānta:

Theme	Nietzsche	Bernardo Kastrup	Advaita Vedānta
Ultimate reality	No simple metaphysical “ultimate reality” is affirmed; Nietzsche is critical of traditional metaphysics	Mind/consciousness is fundamental; matter is not fundamental	Brahman is the ultimate reality
Consciousness	Not treated as an independent cosmic substance	Fundamental; individual minds are dissociated aspects of a universal consciousness	Pure consciousness (Ātman/Brahman) is fundamental
Matter	Nietzsche rejects simplistic metaphysical dualisms, but doesn't say matter is merely an appearance of universal consciousness	Matter is the extrinsic appearance of mental processes	The world is Māyā—dependent/ultimately non-independent appearance
Individual self	The stable, autonomous “self” is questioned; humans are dynamic, embodied drives	Individual minds are dissociated alters within universal consciousness	Individual ego (ahaṃkāra) is ultimately not the true Self
God	Famously declares “God is dead”—traditional Christian God no longer provides a convincing foundation for values	Doesn't require a personal creator God; his view is non-theistic idealism	Brahman is ultimate reality, but not a personal creator God in the ordinary sense
World	A world of becoming, struggle, interpretation and competing drives	A manifestation/appearance of universal consciousness	Empirical reality appears through Māyā; Brahman alone is ultimately real
Goal of life	Self-overcoming, creation of values, affirmation of life	Understand the nature of consciousness and overcome the illusion that matter is fundamental	Mokṣa—realization that Ātman is Brahman
Morality	Rejects universal/inherited morality; values should be critically re-evaluated	Not primarily a moral philosophy	Dharma and ethics matter conventionally, but liberation ultimately transcends egoic identification
Attitude toward suffering	Affirm and overcome suffering; amor fati	Suffering is part of conscious existence, but metaphysics is not centered on overcoming it	Suffering arises from avidyā (ignorance/misidentification); liberation ends its fundamental basis
Rebirth	No central doctrine; eternal recurrence is very different from reincarnation	Not central to his idealism	Saṃsāra/rebirth is central to conventional existence
Big question	How can humanity create values after the collapse of traditional values?	What if consciousness—not matter—is the fundamental reality?	Who am I, and what is ultimately real?
Similarity to Advaita	Both challenge the ordinary conception of the self and inherited assumptions	Very strong metaphysical similarity to non-dual idealism	—
Major difference	Nietzsche is fundamentally concerned with becoming, life, power, creation and value, not liberation into an eternal Absolute	Kastrup gives a modern analytic/metaphysical argument for idealism	Advaita teaches non-dual realization of Brahman as the ultimate truth

The most interesting triangle

You can roughly visualize them like this:

Nietzsche
→ “Don't escape life. Overcome yourself and affirm becoming.”

Kastrup
→ “Don't assume matter is fundamental. Consciousness is fundamental.”

Advaita
→ “Don't mistake the individual ego/world for ultimate reality. Know Ātman as Brahman.”

The Kastrup–Advaita connection is much stronger metaphysically than the Nietzsche–Advaita connection. Kastrup's idealism can sound remarkably close to non-dual philosophies because both place consciousness at the foundation of reality.

But there's an important distinction: Kastrup is not simply presenting Advaita in modern language. His analytic idealism is his own philosophical system, and Advaita has a specific soteriological framework—Ātman, Brahman, avidyā, māyā, mokṣa, etc.—that Kastrup does not simply reproduce.

And Nietzsche would likely object strongly to the Advaitic tendency to treat liberation from identification with the individual self as the ultimate goal. Nietzsche's ideal is not “wake up from individuality”; it is radical self-overcoming and affirmation of life.
