The Medicine Buddha, or Bhaiṣajyaguru, is as his name suggests connected with healing. His mantra exists in both long and short forms. Here is this short form
Om Bekanze Bekanze Maha Bekanze
Radza Samudgate’ Soha”
Bhaiṣajyaguru is one of a set of eight healing Buddhas, which includes Shakyamuni, the historical Buddha. Bhaiṣajyaguru is the head Buddha of the group.
He is Lapis Lazuli blue in color, although sometimes he’s depicted as golden-skinned. He is dressed in the robes of a bhikṣu (monk). His left hand rests in his lap in the mudra (hand gesture) of meditation, while in his right hand, held palm upwards at the right knee, he holds a branch of the healing myrobalan plant.
In his left hand, which rests in his lap in the dhyana (meditation) mudra, he holds a bowl of amrita — the nectar of immortality.
The idea of the Buddha as healer goes back — as a metaphor — to the days of the historical Buddha. It’s said, in fact, that the formula of the Four Noble Truths is based on a medical model of diagnosis, etiology, prognosis, and therapy. The Buddha demonstrates in the historical teachings a good knowledge of anatomy and physiology, at least by the standards of his time, and although he almost certainly wasn’t trained in the medical arts he seems to have had some knowledge of them.
Later texts, like Santideva’s “Guide to the Bodhisattva’s Way of Life,” take up the notion of the Enlightened ones being healers, referring to the Buddha as “the Omniscient Physician who removes every pain.” He also expresses the aspiration, “May I be the medicine and the physician for the sick. May I be their nurse until their illness never recurs.”
