The word 'innocence' means 'incapable of being hurt'. To have a mind that is not capable of being hurt, does not mean that it has built up a lot of resistance - on the contrary, such a mind is dying to everything that it has known in which there has been conflict, pleasure and pain. Only then is the mind innocent; that means it can love. You cannot love with memory, love is not a matter of remembrance, of time.
