According to Osho, blind faith is belief: a second‑hand, unconscious acceptance of ideas without seeing—of the head and therefore blind. Surrender is different: a conscious, love‑born trust that arises from the heart’s own seeing, a personal intimacy with a living presence (master or existence). Surrender dissolves the ego through awareness; blind faith merely masks ignorance.
Blind faith is believing because others say so; surrender is letting go because your own heart has seen and trusts.
