The ultimate truth of phenomena.

( Skt.): The uncontrived realm of all elements of phenomena, both samsara and nirvana; the ultimate space in which all transpires.

Lit., the Dharma element or realm wherever the principles of the Buddha's teaching are operative; phenomena and noumenon and their underlying nature.

has several meanings: 1) The content of the mind; 2) all-encompassing space (matrix) in which all phenomena of any sort arise and fall, without beginning or end; or 3) the universe itself with all its world-systems and societies of beings.

In Mahayana Buddhism, dharmadhātu (chos kyi dbyings) means "realm of phenomena," where emptiness and dependent co-arising are one.
