Because he had proved that neither meditation nor ascetic austerities enabled one to attain the ideal, Śākyamuni saw that no other method that existed at the time could lead to his goal. In reflecting on this, the prince developed three comparisons: transferring light ignited with a fire stick to waterlogged fresh wood, transferring light ignited with a fire stick to ordinary fresh wood, and igniting fire with a fire stick on dry wood. Waterlogged and fresh wood symbolize the heart saturated with desires and worldly attachments. Dry wood symbolizes a heart in which there is no longer desire or attachment to worldly things. The act of igniting fire by means of a fire stick represents diligent effort. The most assiduous effort in ascetic austerities cannot bring enlightenment to a heart saturated with desires and attachments, just as fire struck by means of the fire stick at the cost of great effort cannot be transferred to waterlogged or fresh wood. But since fire can be struck readily by diligent effort with the fire stick on dry wood, so a heart that has already been drained of desires and attachments by equally diligent spiritual effort can attain the ideal goal.

When he understood this, Śākyamuni saw that both meditation practice and ascetic austerities were mistaken. After recovering his physical strength, he prepared a seat with soft grass under an assattha, or bo, tree not far from the town of Gaya and, making a vow not to rise until he attained enlightenment, even if it meant death, sat in meditation.

In the first hours of the night of his enlightenment (the hours from six till ten), he attained wisdom about all past things. In the middle hours (from ten until two in the morning), he attained wisdom about all future things. Then in the final hours (from two until six in the morning), he was freed of all bondage and attained wisdom without illusion. He became a Buddha. And this was the starting point of Buddhism.
