In Buddhism, there is a teaching called the "three bodies" (sanjin), also called the "three properties" or the "three enlightened properties". These are the three kinds of form that a Buddha may manifest as:
1) the Dharma Body (dharmakaya or hosshin) is the form in which a Buddha transcends physical being and is identical with the undifferentiated unity of being or Suchness (Skt. tathata, Jp. shinnyo);
2) the Bliss or Reward Body (sambhogakaya or hojin) is obtained as the "reward" for having completed the bodhisattva practice of aiding other beings to end their suffering and having penetrated the depth of the Buddha's wisdom. Unlike the Dharma Body, which is immaterial, the Bliss Body is conceived of as an actual body, although one that is still transcendent and imperceptible to common people;
3) the Manifested Body (nirmanakaya or ojin) is the physical form in which the Buddha appears in this world in order to guide sentient beings. It is considered that the historical Buddha, Shakyamuni, is nirmanakaya. Honen believed that Amida is sambhogakaya.
