It is felt that a disciplined mind leads to happiness and an undisciplined mind leads to suffering, and in fact it is said that bringing about discipline within one's mind is the essence of the Buddha's teaching.
Dalai LamaThe most important benefit of patience consists in the way it acts as a powerful antidote to the affliction of anger - the greatest threat to our inner peace, and therefore our happiness. The mind, or spirit, is not physical, it cannot be touched or harmed directly. Only negative thoughts and emotions can harm it. Therefore, only the corresponding positive quality can protect it.
Dalai LamaGiving material goods is one form of generosity, but one can extend an attitude of generosity into all one's behavior. Being kind, attentive, and honest in dealing with others, offering praise where it is due, giving comfort and advice where they are needed, and simply sharing one's time with someone - all these are forms of generosity, and they do not require any particular level of material wealth.
