The sacrifice which causes sorrow to the doer of the sacrifice is no sacrifice. Real sacrifice lightens the mind of the doer and gives him a sense of peace and joy. The Buddha gave up the pleasures of life because they had become painful to him.
That's how it will be, except that in reality, both today and later, one will stand there with a palpable body and a real head, a real forehead, that is, for smiting on with one's hand.
Other people have faces; Susan and Jinny have faces; they are here. Their world is the real world. The things they lift are heavy. They say Yes, they say No; whereas I shift and change and am seen through in a second. If they meet a housemaid she looks at them without laughing. But she laughs at me. They know what to say if spoken to. They laugh really; they get angry really; while I have to look first and do what other people do when they have done it.
Real spirituality is going through fire. Real spirituality is rebellion against all that is rotten, against all that is past, against all that is being forced on you by others, against all conditionings. Real spirituality is the greatest rebellion there is. It is risky, it is adventurous, it is dangerous. So beware of pseudo spirituality which is always there, available, easily available at the door.
