According to Osho, liberated souls do not return to nigod or any cyclic state. Nigod belongs to the utterly mechanical, unconscious realm—like water predictably cycling as liquid, steam, and ice. Moksha is total consciousness, a freedom beyond all cycles and laws. Once awakening breaks mechanicalness completely, return is impossible; only within the world of sleep do beings keep circling.
Once you’re fully awake (liberated), you can’t fall back into the unconscious loop called nigod.
