Sangye Menla (in Tibetan), Bhaiṣajyaguru (Sanskrit), more formally Bhaiṣajyaguruvaidūryaprabharāja ("Medicine Master and King of Lapis Lazuli Light"), is the buddha of healing and medicine in Mahayana Buddhism. In the English language, he is commonly referred to as the "Medicine Buddha". The use of the analogy of a Buddha being depicted as a doctor who cures the illness of suffering using the medicine of his teachings appears widely in Buddhist scriptures.
The practice of Medicine Buddha, the Supreme Healer, is not only a very powerful method for healing and increasing healing powers both for oneself and others, but also for overcoming the inner sickness of attachment, hatred, and ignorance, thus to meditate on the Medicine Buddha can help decrease physical and mental illness and suffering.
The Medicine Buddha mantra is held to be extremely powerful for healing of physical illnesses and purification of negative karma. One form of practice based on the Medicine Buddha is done when one is stricken by disease. The patient is to recite the long Medicine Buddha mantra 108 times over a glass of water. The water is now believed to be blessed by the power of the mantra and the blessing of the Medicine Buddha himself, and the patient is to drink the water. This practice is then repeated each day until the illness is cured.
