When Channa had departed, Gautama sought the caves where the hermits dwelt. There he stayed a while, fasting and doing penance, in the hope of finding out in this way the true road to happiness and righteousness. So long did he go without food, and so severely did he inflict torture on himself, that one day he fell down exhausted. Every one thought he was dead, but he recovered after a little while. It seemed to him, when he once more regained consciousness, that this life of self-denial and hardship did not lead to that which he was seeking. So he left off fasting, and took his food again like an ordinary man. This disgusted the few disciples who had been living with him in retirement, and they all fled away and left him to himself. When they had gone, he strolled down to the banks of the neighbouring river. As he went along, the daughter of one of the villagers offered him some food. He took it, and sat down under the shade of a large tree. This tree is known to all Buddhists as the Bo-tree, and is as sacred to them as the cross is to Christians. While sitting under the tree, Gautama thought seriously about the past and the future. He felt very disappointed with his failure and at the loss of his late friends. The evil one came to him again, and whispered to him of love and power, of wealth and honour, and urged him to seek his home, his wife, and his child. For forty-nine days and nights Gautama sat under the Bo-tree, his mind torn with the conflict as to what was his duty. At the end of that time his doubts vanished, his mind cleared, the storm was over, and he had become the "Buddha"--that is, the "Enlightened One." He knew now that it was his duty to go and preach to people the way to happiness and peace, to show them how to avoid misery, and how to conquer even death itself. It would take too long now to tell you what it was that the Buddha preached to those who would listen to him. Some time when you are older you must read this for yourself in another book.
