There are two kinds of happiness - the temporary pleasure derived primarily from material comfort alone and another more enduring comfort that results from the thorough transformation and development of the mind. We can see in our own lives that the latter form of happiness is superior because when our mental state is calm and happy, we can easily put up with minor pains and physical discomforts. On the other hand, when our mind is restless and upset, the most comfortable physical facilities do not make us happy.
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 LamaThe more adept we become at cultivating an altruistic attitude, the happier we will feel and the more comfortable will be the atmosphere around us. But if our emotions fluctuate wildly and we easily give in to hatred and jealousy, even our friends will avoid us. So even for people with no spiritual beliefs, it is important to have a peaceful mind.
