According to Osho, total giving becomes possible only when inquiry is complete and thus free of both belief and doubt. Doubt exists only in opposition to belief; pure search leaves the mind undivided. Seeing that nothing else can be staked but oneself, one risks the whole being—no half-measures—and becomes capable of infinite waiting for the Ultimate.
You can give your all only when your curiosity is so clear it holds no beliefs or doubts—then you can bet everything.
