According to Osho, there was no 'end' of Neo-Sannyas to coincide with any date; he only stopped it calcifying into a religion. A movement must remain alive, individual, and evolving; what was cremated was the dead structure imposed in his absence, not the spirit. Sannyas continues as religionless religiousness—friends, not followers—so calendar coincidences are irrelevant compared with freeing growth from labels and institutions.
It didn’t end; he just threw away the rigid religion cage so the living spirit can keep growing.
