Tushita

It is the heaven where the Bodhisattva Śvetaketu (Pāli: Setaketu, "White Banner") resided before being reborn on Earth as Gautama, the historical Buddha; it is, likewise, the heaven where the Bodhisattva Nātha ("Protector") currently resides, who will later be born as the next Buddha, Maitreya.

Most Buddhist literature holds that Queen Maya died seven days after the birth of her son the Buddha, and was then reborn in the Tushita Heaven.

According to the Visakhuposatha Sutta of the Pali Canon,[4] time runs much differently than on Earth: That which among men is four hundred years, Visakha, is one night and day of the Tusita devas, their month has thirty of those days, their year twelve of those months; the lifespan of the Tusita devas is four thousand of those heavenly years...In Mahayana Buddhist thought, the Tuṣita Heaven is where all Bodhisattvas destined to reach full enlightenment in their next life dwell for a time.

One such reference can be found in the Larger Sutra of Immeasurable Life, a Mahayana text: Each of these bodhisattvas, following the virtues of the Mahasattva Samantabhadra, is endowed with the immeasurable practices and vows of the Bodhisattva Path, and firmly dwells in all the meritorious deeds.

Having left the heavenly palace, he descends into his mother's womb.The Tuṣita heaven is therefore closely associated with Maitreya, and many Buddhists vow to be reborn there so that they can hear the teachings of the Bodhisattva and ultimately be reborn with him when he becomes a Buddha.
