報身 The reward body of the buddha (saṃbhoga-kāya).

saṃbhoga-kāya

(Sanskrit). The Enjoyment Body of a Buddha, the second of a Buddha's three bodies, according to the Mahāyāna trikāya doctrine. The saṃbhoga-kāya is thought to be a more subtle mode of embodiment than the Emanation Body (nirmāṇa-kāya) and thus only visible to Bodhisattvas. Arising from the Truth Body (dharma-kāya), saṃbhoga-kāyas take on the appearance of the many different Buddhas mentioned in Mahāyāna sūtras, such as Amitābha, Akṣobhya, or Vairocana, each one thought to reside in their own particular Pure Land. There, adorned with the 32 major and 80 secondary marks of perfection (see dvātriṃśadvara-lakṣaṇa; anuvyañjana) they communicate the Dharma to select audiences of Bodhisattvas and gods. In later tantric Buddhism, the saṃbhoga-kāya is considered to be the equivalent of the speech vector of a Buddha's activities.
