I never have held death in contempt, though in the course of my explorations I have oftentimes felt that to meet one's fate on a noble mountain, or in the heart of a glacier, would be blessed as compared with death from disease, or from some shabby lowland accident. But the best death, quick and crystal-pure, set so glaringly open before us, is hard enough to face, even though we feel gratefully sure that we have already had happiness enough for a dozen lives.
A man who has once perceived, however temporarily and however briefly, what makes greatness of soul, can no longer be happy if he allows himself to be petty, self-seeking, troubled by trivial misfortunes, dreading what fate may have in store for him. The man capable of greatness of soul will open wide the windows of his mind, letting the winds blow freely upon it from every portion of the universe.
He will see himself and life and the world as truly as our human limitations will permit; realizing the brevity and minuteness of human life, he will realize also that in individual minds is concentrated whatever of value the known universe contains. And he will see that the man whose mind mirrors the world becomes in a sense as great as the world. In emancipation from the fears that beset the slave of circumstance he will experience a profound joy, and through all the vicissitudes of his outward life he will remain in the depths of his being a happy man.
Happiness happens when you fit with your life, when you fit so harmoniously that whatsoever you are doing is your joy. Then suddenly you will come to know: meditation follows you. If you love the work that you are doing, if you love the way you are living, then you are meditative.
When we seek happiness through accumulation, either outside of ourselves--from other people, relationships, or material goods--or from our own self-development, we are missing the essential point. In either case we are trying to find completion. But according to Buddhism, such a strategy is doomed. Completion comes not from adding another piece to ourselves but from surrendering our ideas of perfection.
