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.
The soil in which the meditative mind can begin is the soil of everyday life, the strife, the pain, and the fleeting joy. It must begin there, and bring order, and from there move endlessly. .. You must take a plunge into the water, not knowing how to swim. And the beauty of meditation is that you never know where you are, where you are going, what the end is.
Life is both pleasure and pain, is it not? But why should we cling to pleasure and avoid pain? Why not merely live with both? If you cling to pleasure what happens? You get attached, do you not?
You say you love your wife. You depend on her; she has given you her body, her emotions, her encouragement, a certain feeling of security and well-being. Then she turns away from you; she gets bored or goes off with someone else, and your whole emotional balance is destroyed, and this disturbance, which you don't like, is called jealousy. There is pain in it, anxiety, hate and violence. So what you are really saying is, 'As long as you belong to me I love you but the moment you don't I begin to hate you.
The very word "sorrow" colours the fact of sorrow, the pain of it.
So through identification you have pleasure and pain.
