Tushita Heaven

Tuṣita (Sanskrit, Pāli Tusita) or Tushita is one of the six deva-worlds of the Buddhist Desire realm (Kāmadhātu), located between the Yāma heaven and the Nirmāṇarati heaven. Like the other heavens, Tuṣita is said to be reachable through meditation. It is the heaven where the Bodhisattva Śvetaketu ("White Banner") resided before being reborn on Earth as Gautama Buddha, the historical fourth Buddha. It is, likewise, the heaven where the Bodhisattva Nātha ("Protector") currently resides, who will be reborn as the future fifth Buddha Maitreya.
Most Buddhist scriptures state that Queen Mayadevi died seven days after giving birth at Lumbini to her son Prince Siddhartha, who became Gautama Buddha or the Buddha, and that she was reborn in the Tushita Heaven. Then seven years after the Buddha's enlightenment, Mayadevi came down to visit Tavatimsa Heaven, where the Buddha specifically preached the Abhidharma to her, and to the other gods in the realm.
In Hinduism, the Tushitas are referred to as one of the nine gana deities: adityas, visvedevas, vasus, tushitas, abhasvaras, anilas, maharajikas, sadhyas, and the rudras.

Descriptions
Like all heaven realms in Buddhism, the Tuṣita Heaven is the residence of divine beings or devas. According to the Visakhuposatha Sutta of the Pali Canon, 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...

Buddhist View
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:…
