According to Osho, self-realization doesn’t arise by mentally ‘embracing everything’ or by visualizing God in all—that is fantasy. Enter the nearest door: your own self. Penetrate the I until it dissolves; with the end of I and you, nonduality remains. Then the all is discovered from within, not by adding parts, but by the disappearance of separateness.
Don’t try to include everything; look within until the separate ‘me’ falls away, and oneness shows itself.
