Surely if living creatures saw the results of all their evil deeds, they would turn away from them in disgust. But selfhood blinds them, and they cling to their obnoxious desires. They crave pleasure for themselves and they cause pain to others; when death destroys their individuality, they find no peace; their thirst for existence abides and their selfhood reappears in new births. Thus they continue to move in the coil and can find no escape from the hell of their own making.
To find Buddha, you have to see your nature. Whoever sees his nature is a Buddha. If you don't see your nature, invoking buddhas, reciting sutras, making offerings, and keeping precepts are all useless. Invoking buddhas results in good karma, reciting sutras results in a good memory, keeping precepts results in good rebirth, and making offerings results in future blessings-but no Buddha.
From the scientific view, the theory of karma may be a metaphysical assumption -- but it is no more so than the assumption that all of life is material and originated out of pure chance
We are the makers of our own lives. There is no such thing as fate. Our lives are the result of our previous actions, our karma, and it naturally flows that, having been ourselves the makers of our karma, we must also be able to unmake it.
We manage to swallow flesh only because we do not think of the cruel and sinful thing that we do. There are many crimes which are the creation of man himself, the wrongfulness of which is put down to their divergence from habit, custom, or tradition. But cruelty is not of these. It is a fundamental sin, and admits of no argument or nice distinctions. If only we do not allow our heart to grow callous, its protest against cruelty is always clearly heard; and yet we go on perpetrating cruelties easily, merrily, all of us - in fact, anyone who does not join in is dubbed a crank.
