Post on the Lion’s Roar, What is the Rainbow Body?
“In Vajrayana traditions of Tibetan Buddhism, tangible matter is considered to be made up of five elements: space, air, fire, water, and earth. As described in Tibetan literary sources, including The Tibetan Book of the Dead, the elemental energies that make up the cosmos are understood to be undifferentiated from those that make up the human body. Therefore, the body is simultaneously an individual person and the cosmic whole.”
