The nature of the mind is such that if certain mental qualities are developed on a sound basis, they not only remain, but they also increase. In fact, once properly developed, the mind's good qualities eventually increase indefinitely. Therefore spiritual practice brings us long-term happiness and inner strength.
Dalai LamaThe practice of altruism is the authentic way to live as a human being, and it is not just for religious people. As human beings, our purpose is to live meaningful lives, to develop a warm heart. There is meaning in being everyone's friend. The real source of peace amongst our families, friends and neighbours is love and compassion.
