According to Osho, Ahmak Ahmadabadi ultimately became his sannyasin: after almost going to Kashi for a sorrow-born renunciation, a burst of laughter cracked his seriousness, and he returned to Osho. Osho rejects grim, hollow religiosity; his sannyas is celebrative—laughing, dancing, ecstatic—chosen from joy, not misery. He even says Ahmak sits there, under a changed name.
Yes—he came back and became Osho’s sannyasin, because true sannyas is joyful, not gloomy.
