According to Osho, liberation (moksha) is possible only in the human yoni: animals lack developed awareness to practice, and devas lack a physical body—both essential links for sadhana. Thus animals must evolve into humans, and gods must return to human birth to be freed. The human state, poised at a crossroads, uniquely offers choice, effort, and the transformative tension between pain and pleasure necessary for awakening.
Only as a human can you get free; animals don’t have enough awareness yet, and gods don’t have bodies to practice, so both must become human to reach liberation.
