Delusions are states of mind which, when they arise within our mental continuum, leave us disturbed, confused and unhappy. Therefore, those states of mind which delude or afflict us are called 'delusions.'
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.
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.
