Visualise yourself in your ordinary body, with your heart at the center of your chest, inverted, pointing upwards. Inside your heart is a white, eight-petalled lotus.
At its center is a moon disc, upon which is seated the Healing Buddha in the aspect of the supreme transformation. His body is clear and in the nature of dark blue light, and he holds an arura plant in his right hand and a begging bowl in his left hand.
In front of the Healing Buddha is the white medicinal goddess, Actualized Wisdom; to his right is the yellow medicinal goddess, Simultaneous Wealth; behind him is the red forest goddess, Peacock’s Throat; to his left is the green tree goddess, Radiant One.
Each goddess is in the nature of blissful radiant light and has one face and two arms. An arura plant is in each of the goddess’s right hands, with a vase adorned with various ornaments in the left hand. The four goddesses sit cross-legged, not in the full vajra position but in the aspect of offering respect to the Healing Buddha.
Then make this request.
O DESTROYER, COMPLETE IN ALL QUALITIES AND GONE BEYOND
AND YOU FOUR MEDICINAL GODDESSES,
PLEASE PACIFY IMMEDIATELY THE ILLNESSES WHICH AFFLICT ME NOW
AND HELP ME TO AVOID ALL FUTURE SICKNESSES.
Light rays of the appropriate colour emanate from each of the five deities at your heart. Your heart and body are full of blissful light, which perfectly purifies all diseases, spirit harms, and negative actions and their imprints.
Beams of five coloured light radiate from all the pores in your body, while nectar flows down from the Healing Buddha’s begging bowl and the vases held by the four goddesses, completely filling your heart and body.
Generate the strong recognition that you have vanquished disease forever and will never be sick again. While concentrating single-pointedly on this visualization, recite the short or long Healing Buddha mantra seven, twenty-one, one hundred and eight, or more times.

If you are sick, after you have finished reciting the mantra, put some saliva in your left palm, rub it on the tip of your right ring finger, place the tip of this finger at the entrance of your right and left nostrils, where the so-called All-Doing King Nerve can be found, and apply the saliva to the afflicted parts of your body. Then recite as many mantras of the Sanskrit vowels and consonants as possible, along with the mantra of the Heart of Dependent Arising.
