On a full-moon day in May, he sat under the Bodhi tree in deep meditation and said. “I will not leave this spot until I find an end to suffering.” During the night, he was visited by Mara, the evil one, who tried to tempt him away from his virtuous path. First he sent his beautiful daughters to lure Gautama into pleasure. Next he sent bolts of lightning, wind and heavy rain. Last he sent his demonic armies with weapons and flaming rocks. One by one, Gautama met the armies and defeated them with his virtue.
As the struggle ended, he realized the cause of suffering and how to remove it. He had gained the most supreme wisdom and understood things as they truly are. He became the Buddha, 'The Awakened One'. From then on, he was called Shakyamuni Buddha.
