According to Osho, Vedanta’s final conclusion (veda-anta) is Advaita: there is only one reality, Brahman, and your inmost self is not other than That—Tat Tvam Asi, Aham Brahmasmi. All separateness is a play of mind (maya); in awakening as the witnessing consciousness, the seeker discovers wholeness here-now, not as belief but as lived realization continuing from the Upanishads.
Deep down, you and everything you see are the same one life; noticing this ends the feeling of being separate.
