(Sanskrit; also known as Jnanakaya) The Essence-Kaya, the Essence-Body, the unifying essence of the trikaya (bodies of the Buddha) formed by liberating the kayas of light that which the Hebrews call "Igneous Particles", "Haishim" (literally, "the fires") or "Igneous Souls”, from the skandhas (psychological aggregates). It is the body of liberation, the Rainbow Body. The Svabhavikakaya is counted as the Fourth Kaya, it is the receptacle of the three Solar Kayas, or the unity or non-separateness of the three kayas. In other teachings, it is called theomertmalogos.
