The various features and aspects of human life, such as longevity, good health, success, happiness, and so forth, which we consider desirable, are all dependent on kindness and a good heart.
Dalai LamaAlthough you can find certain differences among the Buddhist philosophical schools about how the universe came into being, the basic common question addressed is how the two fundamental principles-external matter and internal mind or consciousness-although distinct, affect one another. External causes and conditions are responsible for certain of our experiences of happiness and suffering. Yet we find that it is principally our own feelings, our thoughts and our emotions, that really determine whether we are going to suffer or be happy.
Dalai LamaThe colors of light are infinite through refraction, yet they all come from the same source. Thus I cannot detach myself from the wickedest soul, nor fail to identify with the most virtuous.
