Purification, abstention and restraint can be the result of moral obligations, obedience to religious customs or self-punishment. They can also be choices simply based upon one’s direct experience, which proves that certain attitudes and behaviours keep causing pain and misery. In this case these attitudes are released only in order to experience happiness and peace, rather than as an act of sacrifice or renunciation. Amongst all the possible forms of abstention and release, letting go of the temptation to hold grievances towards ourselves and others is probably the most powerful. This involves releasing the tendency to attack others or defend ourselves in any way, including being envious, jealous and competitive. Again here the purpose is not becoming a holy or wise person. It is merely to be happy.
