(Sanskrit) From निर्माण Nirmana, "creation, producing, formation, making, transformation," and काय kaya, "body."
Also called “creation body” or “manifestation body.”
In Buddhism, one of the "bodies" of a buddha corresponding to a very subtle level of manifested existence. As such, it corresponds to a level of nature that other beings can perceive or experience with training, specifically during dream state, and in preparation for the process of death, during which one who is prepared can recognize the experience and utilize it as a doorway to a better level of existence.
Nirmanakaya corresponds in Kabbalah to the sephirah Binah.
"Those who renounce the happiness of Nirvana for the love of humanity, those who have the Nirmanakaya body or vehicle of solar transformation are the authentic Bodhisattvas who, indeed, walk along the Direct Path and know the Word of the Lord." —Samael Aun Weor, The Gnostic Bible: The Pistis Sophia Unveiled
"On that patio, around the sacred table, a group of Nirmanakayas were seated… Those ineffable beings were distilling happiness. Oh God! What beautiful tunics, vestures of paradise! What divine countenances!" —Samael Aun Weor, Cosmic Teachings of a Lama
