Right morality or right discipline on the Buddhist path is based on egolessness. If there is no one to impose discipline and no one to impose discipline on, then there is no need for discipline in the ordinary sense at all! If there is a tree, there must be branches. However, if there is no tree, there are no such things as branches. Likewise, if there is no ego, a whole range of projections becomes unnecessary. Right discipline is that kind of giving up process. It brings us into complete simplicity.
