The Middle Length Discourses of the Buddha - Bhikkhu Nanamoli [20]
The good destinations in the sense-sphere realm are the human world and the heavenly planes. The latter are sixfold: the gods under the Four Great Kings; the gods of the Thirty-three (tāvatiṁsa), who are presided over by Sakka, a Buddhist metamorphosis of Indra, depicted as a devotee of the Buddha, faithful, but prone to negligence (MN 37); the Yāma gods; the gods of the Tusita heaven, the abode of the Bodhisatta before his final birth (MN 123); the gods who delight in creating; and the gods who wield power over others’ creations. The last is said to be the abode of Māra, the Tempter in Buddhism, who besides being a symbol for Desire and Death, is also regarded as a powerful deity with evil designs, keen to prevent beings from escaping the net of saṁsāra. The kammic cause for rebirth into the good destinations of the sense-sphere realm is the practice of the ten courses of wholesome action, defined at MN 9.8 and in MN 41.
In the fine-material realm the grosser types of matter are absent and the bliss, power, luminosity, and vitality of its denizens are far superior to those in the sense-sphere realm. The fine-material realm consists of sixteen planes, which are the objective counterparts of the four jhānas. Attainment of the first jhāna leads to rebirth among Brahmā’s Assembly, the Ministers of Brahmā and the Mahā Brahmās, according to whether it is developed to an inferior, middling, or superior degree. Baka the Brahmā (MN 49) and Brahmā Sahampati (MN 26, MN 67) seem to be residents of the last-named plane. The suttas mention especially the divine abodes as the path to the company of Brahmā (MN 99.24–27). Attainment of the second jhāna in the same three degrees leads respectively to rebirth among the gods of Limited Radiance, of Immeasurable Radiance, and of Streaming Radiance; the third jhāna to rebirth among the gods of Limited Glory, of Immeasurable Glory, and of Refulgent Glory. The fourth jhāna ordinarily leads to rebirth among the gods of Great Fruit, but if it is developed with a desire to attain an insentient mode of existence, it will conduce to rebirth among the non-percipient beings, for whom consciousness is temporarily suspended. The fine-material realm also contains five special planes that are exclusively for the rebirth of non-returners. These are the Pure Abodes—the Aviha, the Atappa, the Sudassa, the Sudassī, and the Akaniṭṭha. In each of these planes in the fine-material realm the lifespan is said to be of enormous duration and to increase significantly in each higher plane.
The third realm of being is the immaterial realm, where matter has become non-existent and only mental processes exist. This realm consists of four planes, which are the objective counterparts of the four immaterial meditative attainments, from which they result and whose names they share: the bases of infinite space, infinite consciousness, nothingness, and neither-perception-nor-non-perception. The lifespans ascribed to them are respectively 20,000; 40,000; 60,000; and 84,000 great aeons.
In Buddhist cosmology existence in every realm, being the product of a kamma with a finite potency, is necessarily impermanent. Beings take rebirth in accordance with their deeds, experience the good or bad results, and then, when the generative kamma
