How to achieve happiness? For a start, it is possible to divide every kind of happiness and suffering into two main categories: mental and physical. Of the two, it is the mind that exerts the greatest influence on most of us. Unless we are either gravely ill or deprived of basic necessities, our physical condition plays a secondary role in life. If the body is content, we virtually ignore it. The mind, however, registers every event, no matter how small. Hence we should devote our most serious efforts to bringing about mental peace. From the experience of Dalai Lama, he found that the greatest degree of inner tranquility comes from the development of love and compassion.
