According to Osho, separation isn't a stage to cross later—you’re already in it as the ego’s delusion. Union with the Divine is not achieved by “joining” but by the vanishing of the separate self; what is, is already in God. Through right understanding, remembrance, and awareness, the illusion dissolves and the ever-present oneness is revealed.
You’re not really apart from God; let go of the idea of a separate ‘me’ and the always-present oneness shows itself.
