1. His Promise to Take Birth in the Human Realm
Before the Buddha was born into this world as Shakyamuni, he was a bodhisattva in the Tushita heaven (home of the contented gods). His name there was Shvetaketu ("White Banner"). From here he witnessed the dark ages engulfing the human realm, leading to its spiritual impoverishment. Moved to compassion like a true bodhisattva, he vowed to manifest himself in the sentient world and relieve people from their sufferings.
2. Queen Maya's Dream
The bodhisattva's descent from the Tushita heaven occurred as a dream to Mayadevi. In this dream, a white elephant approached and touched her right side with its trunk. Through this symbolic act, the bodhisattva entered the womb of Mayadevi and impregnated her.
3. Birth of the Buddha
ccording to legend, Buddha was born from the right side of his mother. Immediately upon his birth, he stood up and took seven steps, and wherever his feet touched the earth lotuses sprang up. Raising his hand he said: "Worlds above, worlds below, there's no one in the world like me."
4. A Youth Dedicated to the Mastery of Learning and Athletics
As the son of the king, Siddhartha was provided with the finest upbringing. His life had ample quantities of both opportunity and security. He received the finest education and mastered all lessons taught to him. In his younger years, he excelled in sports and other contests of skill. The vigorous training befitted the grooming of a future monarch. He was said to particularly excel on the horse and with the bow.
5. The Skillful Conduct of Worldly Affairs
Narrative paintings depict him at court, consulting his experienced father in the skilful conduct of material affairs.
6. The Four Encounters
Having been warned by the court astrologers that his son may well give it all up and choose the path of meditation, Buddha's father tried his best to shield him from the harsh realities of life.
7. The Renunciation of Worldly Life
Having made the decision, Siddhartha requested his father to allow him to proceed in his quest for truth.
8. The Six Years of Austerities
Wandering in his search for enlightenment, Buddha came to a pleasant hermitage by a lovely stream, where, for six years, he joined five mendicants in a way of discipline based on progressively severe fasting. He ate a single grain of rice for each of the first two years, drank a single drop of water for each of the second two years, and took nothing at all during the last two. Consequently, his bones stuck out like a row of spindles, and when he touched his stomach, he could almost feel his spine. His hair fell out and his skin became withered.
9. The Defeat of Mara
Hearing this solemn vow, Mara, the Buddhist manifestation of death and desire, felt threatened. Mara's power over sentient beings originated from their attachment to sensuous pleasures and the consequent fear of death which lead to intense suffering. Enlightenment would free Siddhartha from Mara's control and provide an opportunity for others to free themselves also by emulating him.
10. The Proclamation of the Teachings
Having gained enlightenment, Gautama came to be called Shakyamuni, or the silent lion, indicating the explosive potential he carried within himself. He first went up to Sarnath near Varanasi where he met the five disciples with whom he had previously traversed the path of asceticism. Though they had deserted him after their failed experiment, the unearthly glow from his body now attracted them. Hearing his discourse, they became his first followers.
11. The Descent from the Trayatrimsa Heaven
Queen Maya, after her death, was said to have been reborn in the Trayatrimsa heaven. Having attained enlightenment, Buddha decided to ascend to the Trayatrimsa heaven, literally the heaven of thirty-three gods, to visit his mother. The name 'thirty-three' derives from the fact that it is the residence of the 33 gods of Hinduism, an ancient notion, having roots in Vedic thought. With three strides Buddha reached the heaven, where he preached before the divine congregation, including his mother, for several months.
12. The Passage into Parinirvana
Traveling great distances to disseminate his teachings, Buddha finally reached the city of Kushinagara, where he asked his disciples to spread a couch for him in a grove. He lay there, reclining on his right side, facing west, with his head supported by his hand.
Shakyamuni realized clearly that death was approaching. Towards midnight of the same day, the event known in Buddhist terminology as the Parinirvana, or "Final Nirvana," took place. It was a full-moon night and also his eightieth birthday. The Enlightened One passed through progressively higher planes of meditation until he attained entry into Parinirvana.
