Bhaisajya-guru, Lapis Lazuli Radiance Buddha, Master of Healing, taught the "Four Treatises on Medicine," which form the basis of the Tibetan healing arts. His color is the blue of lapis lazuli. The begging bowl in his left hand is made of lapis and contains the elixir of immortality. His right hand makes the gesture of giving and holds a branch of myrobalan, the yellow fruit of which is said to cure all illnesses. To invoke healing power it is sufficient to call the name of Medicine Buddha. With this, if one is not immediately healed, one can count on improved karma in one's next lifetime.
