This is the short version of the Medicine Buddha Mantra, which is known as the Medicine Budddha Heart Mantra:
(Tadyathā) Om Bhaishajye Bhaishajye Mahābhaishajye Bhaishajye Bhaishajye Rāja Samudgate Svāhā
When pronounced by Tibetan buddhists, it sounds like:
(Tah-yah-tah) OM, beck-and-zay beck-and-zay, mah-hah beck-and-zay beck-and-zay, rod-zah sah-moo-gah-tay, so-hah!
Here's Lama Zopa on the recitation of the Medicine Buddha mantra:
"The Medicine Buddha mantra is recited for success. Since we have many problems and want to succeed we need to recite the Medicine Buddha mantra every day. It can help us eliminate the problems, unhappiness and suffering we don’t want and gain the success, happiness, inner growth and realizations of the path that we do.
"Lord Buddha told his attendant Ananda that even animals who hear the Medicine Buddha mantra will never be reborn in the lower realms. The highly attained Kyabje Chöden Rinpoche, who has completed the entire path to enlightenment, said recently that if you recite the Medicine Buddha mantra at the time of death you will be reborn in the pure land. Therefore, it is to be recited not only for healing but also to benefit people and animals all the time, whether they’re living or dying.
"If you recite the Medicine Buddha mantra every day you will purify your negative karma and this will help you never to be reborn in the lower realms. If you don’t purify your negative karma, then when you die you will be reborn in the lower realms as a hell being, hungry ghost or animal and will have to suffer again and again without end. Therefore you need to purify your negative karma right now. If you cannot bear even the present suffering of the human realm—which is blissful joy compared to that of the lower realms—how will you be able to bear the intense suffering of the lower realms, which is unimaginably unbearable, lasts for an incredible length of time and a billion times worse than all the human sufferings put together.
"Since reciting the Medicine Buddha mantra saves you from all these sufferings it is much more precious than skies of gold, diamonds, wish-fulfilling jewels and zillions and zillions of dollars. Material wealth counts for nothing because it can’t purify negative karma. Even if you possessed that much wealth, simply reciting or even hearing the Medicine Buddha mantra just once would be far more precious because it would leave an imprint of the entire path to enlightenment on your mind, help you gain realizations of the path, eradicate all your gross and subtle defilements and cause you to achieve enlightenment.
"The Medicine Buddha mantra can help you liberate numberless sentient beings from the vast oceans of suffering and bring them to enlightenment, so you should recite it with absolute trust in the Medicine Buddha, knowing that he will completely take care of your life and heal you in every way and that he is always with you—in your heart, on your crown and right there in front of you. There is not one second that the Medicine Buddha does not see or have compassion for you.
