It is clear that the greater your sense of altruism, the more you work for the welfare of others, the greater will be your own satisfaction. And when you come to die you’ll be able to go with confidence. As you dedicate yourself to working for others, your own interests will incidentally be fulfilled. Selfishness and self-centredness, on the other hand, lead to anxiety and suspicion, poor health and a decline in well-being.
May the supreme and precious awakening mind
Arise where it has not yet arisen.
And where it has declined or does not exist,
May it flourish and keep growing.
~His Holiness the Dalai Lama
