This is the tenth entry from my fieldwork diary. The original date is 04.06.2010.
"Medicine Buddha protects living beings from physical and mental sickness. He is dark blue and has a vase with nectar (healing herbs) in his left hand. When we recite the Medicine Buddha mantra we receive the healing energy of these herbs.
You must visualize the sick bodypart as dark blue and formless, and chant this mantra so that the healing energy of these herbs will go to the sick bodypart.
The 3 poisons come from our ignorance. Ignorance is like darkness. If you feed these poisons you become ill. The cause of various sicknesses is ignorance, anger, desire etc (the 5 poisons). If you want a long life you should help other sentient beings. Read and meditate on the meaning of the mantra. This mantra should be sent out to all sentient beings in the universe.
You can even do a one-day Medicine Buddha retreat at your countryside. Drink water, eat vegetables but don't have any meat. Meditation helps us to have a better understanding and to improve our memory."
That was on the day before he went on his summer vacation. We were all a bit sad that he was leaving but he replied, "You should be happy for me. I am going on holiday." :)
