Definition
Celestial manifestations
The Sambhogakaya is a "subtle body of limitless form". Both "celestial" Buddhas such as Bhaisajyaguru and Amitābha, as well as advanced bodhisattvas such as Avalokiteśvara and Manjusri can appear in an "enjoyment-body." A Buddha can appear in an "enjoyment-body" to teach bodhisattvas through visionary experiences.
Those Buddhas and Bodhisattvas manifest themselves in their specific pure lands. These worlds are created for the benefits of others. In those lands it is easy to hear and practice the Dharma. A person can be reborn in such a pure land by "the transfer of some of the huge stock of 'merit' of a Land's presiding Buddha, stimulated by devout prayer.
One of the places where the Sambhogakāya body appears is the extra-cosmic realm or pure land called Akaniṣṭha. This is one of the highest realms of the Śuddhāvāsa devas.
Absolutely seen, only the Dharmakāya is real; the Sambhogakāya and Nirmanakaya are "provisional ways of talking about and apprehending it".
