Mahamaya, Siddhartha's mother [the wife of a great king of the Indian Sakyan clan], had a premonitory dream before giving birth to him: A magnificent white elephant with six tusks descended from the heavens surrounded by a chorus of beatific praises. The elephant approached her, its skin white as mountain snow. It held a brilliant pink lotus flower in its trunk, and placed the flower within the queen's body. Then the elephant, too, entered her effortlessly, and all at once she was filled with deep ease and joy.
The king summoned all the local holy men to divine the meaning of this dream. Their conclusion: 'Your majesty, the queen will give birth to a son who will be a great leader. He is destined to become either a mighty emperor who rules throughout the four directions, or a great Teacher who will show the Way of Truth to all beings in Heaven and Earth.'
It was the custom in those days for a woman to return to her parents' home to give birth there. Along the way she stopped to rest in the garden of Lumbini. The forest there was filled with flowers and singing birds. Peacocks fanned their splendid tails in the morning light. Admiring an ashok tree in full bloom, the queen walked toward it, when suddenly feeling unsteady, she grabbed a branch of the ashok tree to support her. Just a moment later, still holding the branch, Queen Mahamaya gave birth to a radiant son."
The story goes that sages arrived at the scene and washed the baby in perfumed water (which is why practitioners of Zen and other Mahayana schools celebrate the birthday by pouring water over a figure of the baby Buddha). Then Mahamaya's attendants wrapped him in silk and carried him to the palace. But seven days after the birth, Mahamaya died (there is no account of how or why), and her sister, Mahapajapati, who was also married to the Buddha's father, became his surrogate mother. After the Buddha's awakening, when he began to teach, Mahapajapati became his first woman disciple and led the order of bhikshunis, or ordained nuns.

... [In some accounts] It is said that auspicious signs herald his birth, the sky was clear with brilliant sunshine, flowers bloomed and birds sang. Directly after his birth nine heavenly dragons appeared and emitted two steams, one cool and one warm, of the purest fragrant rain from their mouths that gently cascaded to bathe the newly born Prince. The baby Prince immediately took seven steps and seven lotus flowers sprang from beneath his feet.
Flowers drifted down from the heavens. [The flowers in this scene are said to be the original of the name "Flower Festival"] The young Prince purified in body and mind from the rain, pointed one hand towards the heavens and one towards the earth and he said,
"Heaven above and earth beneath, I am the Honoured One, the One who liberates all who suffer in the Three Realms."
