(4) The fetter of sensuality or fleshly lust. The belief that fleshly lusts war against the soul is not peculiar to Buddhism. The difficulty for most religions, and indeed for most men, is to hit the man between rigorous asceticism and moral laxity. Buddha, who regarded the "life of mortification" as "unreal" and "unworthy," carefully abstained from overstraining human nature in that particular direction. It was only in the case of the "monk," or "religious devotee," that complete renunciation of the pleasures of the flesh was enjoined. But in the third stage, "the path, of those who will return to earth no more," every one is in a sense a religious devotee; and there can be little doubt, I think, that in that stage the final extinction of lust was contemplated. If so, that achievement would be the consummation of a long course--perhaps pursued through many lives--of continence and self-control.
(5) The fetter of ill-will. The disciple has to subdue all the feelings of anger, resentment, envy, jealousy, hatred, and the like, which spring from his sense of separateness from the rest of mankind, or rather from the rest of living things, and from his subsequent reluctance to identify himself with the Universal Life. In other to get rid of those feelings, a spiritual exercise was prescribed by the early Buddhists, which is eminently characteristic of the general spirit of Buddhism.
"He [the disciple] lets his mind pervade one quarter of the world with thoughts of love, and so the second, and so the third, and so the fourth. And thus the whole wide world, above, below, around and everywhere, does he continue to pervade with heart of love, far-reaching, grown great, and beyond measure. Just as a mighty trumpeter makes himself heard and without difficulty towards all the four directions, even so of all things that have shape or form, there is not one that he passes or leaves aside, but regards them all with mind set free and deep-felt love." The exercise is then repeated, substituting each time for love, first pity, then sympathy, then equanimity. By this means the strength of the fifth fetter is gradually weakened, and at last destroyed.
The whole of the Second and Third Stages is occupied with the struggle against the many enemies of the higher life who fight under the banners of sensuality and ill-will. When all of these have been finally conquered, the disciple enters the Fourth Stage, "the path of the Holy Ones, or Arahats." There he breaks, one by one, the five remaining fetters, to wit:
(6) The desire for life--for separate life--in the worlds of form.
(7) The desire for life--for separate life--in the formless worlds.
(8) Pride.
(9) Self-Righteousness.
