Here are the words for Medicine Buddha Mantra:
Tayata Om Bekandze
Bekandze Maha BeKanze
Radza Samudgate Soha
Here is the meaning behind the words:
Bekandze means eliminating pain, maha bekandze means great eliminating of pain. One explanation of the meaning of the first bekandze is that it refers to eliminating the pain of true suffering, not just of disease but of all problems. It eliminates the pain of death and rebirth that are caused by karma and disturbing thoughts. The first bekandze eliminates all the problems of body and mind, including old age and sickness.
The second bekandze eliminates all the true cause of suffering, which is not external but within the mind. This refers to karma and disturbing thoughts. It is the inner cause that enables external factors such as food and exposure to sunlight to become conditions for disease.
The phrase, maha bekandze, or “great eliminating,” refers to eliminating even the subtle imprints left on the consciousness by disturbing thoughts.
The Medicine Buddha mantra actually contains the remedy of the whole graduated path to enlightenment. The first bekandze contains the graduated path of the lower capable being in general; the second bekandze, the graduated path of the middle capable being in general; and maha bekandze, the graduated path of the higher capable being. The whole graduated path from the beginning up to the peerless happiness of full enlightenment is contained in the Medicine Buddha Mantra.
