Man is not content to create suffering only for himself, but he is relentlessly zealous in creating suffering for his fellowmen. Man seeks his own happiness even at the cost of the happiness of others, thus giving rise to cruelty and unending wars. As long as he thinks only of his own happiness he does not find it. In the pursuit of his own individual happiness the limited self of man becomes accentuated and burdensome. When man is merely selfish he can, in the false pursuit of separate and exclusive happiness, become utterly callous and cruel to others, but this recoils upon him by poisoning the very spring of his life. Loveless life is most unlovely, only a life of love is worth living.
If a man is desireless he will not only eliminate much suffering which he causes others, but also much of his own self-created suffering. Mere desirelessness, however, cannot yield positive happiness, though it protects man from self-created suffering and goes a long way towards making true happiness possible.
True happiness begins when a man learns the art of right adjustment to other persons, and right adjustment involves self-forgetfulness and love. Hence arises the spiritual importance of transforming a life of the limited self into a life of love.
