According to Osho, when one reaches and passes beyond the last center of acceptance, the mind dissolves and the inner voice urging 'go further' disappears. It is a point that is no-place: no self, no question, no movement remains. Every stage is to be crossed, and here even the seeker is gone—so the idea of 'further' cannot arise.
At the very last step, the thinking mind and the ‘me who wants more’ vanish, leaving only silent nothingness—so there’s no next step.
