According to Osho, a spiritual explosion is a sudden, causeless break with the past in which the mind and ego fall away, the old ‘you’ dies, and something wholly new is created. It cannot be produced by effort or understood by the mind; your only 'doing' is non-doing—becoming absent, vacant—so the creative, discontinuous new can arise.
Your old self drops all at once and a fresh you appears, but only when you stop trying and stop getting in the way.
