He horrified his companions by demanding ordinary food and refusing to continue his mortifications. He had realized that whatever truth a man may reach is reached best by a nourished brain in a healthy body. Such a conception was absolutely foreign to the ideas of the land and age. His disciples deserted him, and went off in a melancholy state to Benares. Gautama wandered alone. When the mind grapples with a great and intricate problem, it makes its advances step by step, with but little realization of the gains it has made, until suddenly, with an effect of abrupt illumination, it realizes its victory. So it happened to Gautama. He had seated himself under a great tree by the side of a river to eat, when this sense of clear vision came to him. It seemed to him that he saw life plain. He is said to have sat all day and all night in profound thought, and then he rose up to impart his vision to the world. He went on to Benares and there he sought out and won back his lost disciples to his new teaching. In the King’s Deer Park at Benares they built themselves huts and set up a sort of school to which came many who were seeking after wisdom. The starting point of his teaching was his own question as a fortunate young man, “Why am I not completely happy?” It was an introspective question. It was a question very different in quality from the frank and self-forgetful _externalized_ curiosity with which Thales and Heraclitus were attacking the problems of the universe, or the equally self-forgetful burthen of moral obligation that the culminating prophets were imposing upon the Hebrew mind. The Indian teacher did not forget self, he concentrated upon self and sought to destroy it. All suffering, he taught, was due to the greedy desires of the individual. Until man has conquered his personal cravings his life is trouble and his end sorrow. There were three principal forms that the craving for life took and they were all evil. The first was the desire of the appetites, greed and all forms of sensuousness, the second was the desire for a personal and egotistic immortality, the third was the craving for personal success, worldliness, avarice and the like. All these forms of desire had to be overcome to escape from the distresses and chagrins of life. When they were overcome, when self had vanished altogether, then serenity of soul, Nirvana, the highest good was attained.
