Men are tied up to their families and possessions more helplessly than in a prison. There is an occasion for the prisoner to be released, but householders entertain no desire to be relieved from the ties of family. When a man's passion is aroused nothing prevents him from ruining himself. Even into the jaws of a tiger will he jump. Those who are thus drowned in the filth of passion are called the ignorant. Those who are able to overcome it are saintly Arhats.
