A transcription of the Sanskrit homa， which means "burning." Fire-worshipping brahmans thought that fire was the mouth of heaven and that if they offered things to the fire， heaven would give benefits to men. Esoteric Buddhists 密宗 adopted this method. They make a fire with firewood so that this fire， symbolizing wisdom， may burn the afflictions as well as demonic curses. To perform this， the trinity of subject （the Buddha）， fireplace， and worshipper is necessary. If the worshipper's actions of body， mouth， and mind are completely pure， the corresponding actions in the world will be pure and every affliction and curse will be eliminated.
