The assembly of the Seven Medicine, or Healing, Buddhas, whose function is to release living beings from outer and inner sickness. The principal Medicine Buddha, or Medicine Guru, has a body of blue wisdom light indicating that he is an emanation of the healing power of all the Buddhas; his left hand holds a bowl filled with medicinal nectar and his right hand holds a medicinal plant. Through relying upon Medicine Buddha with faith we develop a special power of body, speech and mind, which we can then use to help others through healing actions.
