It is because man clings to things which cannot fully satisfy him, such as the love of family, the desire for wealth and fame, the wish to be reborn in a heaven (all of which are classed together in Buddhism), that he has to go on being reborn. This is the Buddhist doctrine of _Kamma_. Hinduism, like much orthodox Christianity, thinks of a "soul" which dwells in the body. The Hindu thinks of it as passing from one body to another in the process of transmigration. The view of Buddhism is rather that the "ego" of man is a stream of mental energy, the direction of which is under his own control. If he dies full of _tanhā_, cleaving to the things of this world, he will surely be reborn to some sort of misery. If, on the other hand, he dies detached from human interests and open-eyed to the worthlessness of temporal things, he will eventually be set free from the entanglement of life, as we know it on earth, and will pass into _Nibbāna_. Of this goal one can only say with assurance that it is unlike anything known to mortal man,[10] and that its essence is moral purity. 6. Its Conception of Bliss is realisable in this Life. But Gotama was not concerned with the next life so much as with this. He laid emphasis also upon the wonderful joy and peace which the fixed purpose to achieve _Nibbāna_ had caused him to experience. This was the real relief from suffering, which he had in mind. "Whoso is pure from all _tanhā_, he is in _Nibbāna_." This he preached with great conviction and enthusiasm, declaring that men might aim in this life to attain the position of an _arhat_ (saint) and actually enter into the preliminary experience of _Nibbāna_. It is this aspect of Buddhism which makes it a true religion. Its joy and power can be experienced in the midst of the world's pain. So it is called an "Island," a "Refuge," where the drowning man may escape, or a "Cool Retreat," whither one may fly from a world in flames. 7. Buddhism is a Religion of Enlightenment and Reason. Buddhism exhibits salvation as, first of all, a way of understanding. It is a religion of analysis, which bids man see life steadily and see it whole, by first taking it to pieces! When one looks at the body, what is it, says Buddhism, after all, that we should regard ourselves as attached to it? There are so many bones, so many tendons, so much skin, so many juices. If a man views the body with an anatomical eye, he will see it as it really is; disgust will arise in him which will lead him out into detachment. A Buddhist is sometimes urged to practise the habit of sitting in cemeteries or among reminders of the dead, or to have a skeleton near at hand, in order that he may meditate upon the transient nature of all that is mortal. Similarly he is to dispel anger or lust by asking, "Who is it I am angry with, after whom do I lust, but a bag of bones?" It seeks to dispel passion by reason. 8. It has a strong Moral Code: The "Four Noble Truths," and the "Eight-fold Path."
