liberation through knowledge
Brahman is the only reality
Atman is identical to Brahman
ignorance (avidya) causes bondage
the world is Maya (illusion)
absolute reality is paramarthika
empirical reality is transactional (vyavaharika)
neti neti (not this, not this) method
no eternal difference between soul and God
renunciation (sannyasa) as a path to knowledge
ultimate reality is attributeless (nirguna) Brahman
