Visualization of Light
Rinpoche gave the following advice to a student, whose father has cancer.
My very dear John,
Thank you for your kind note. I checked and it is very good if you become a monk, and very good if you keep your vows well. It is better to stay in a monastery or supportive environment with other Sangha for the first three to five years.
Regarding your father’s cancer, visualize a large or small stupa, full of light that is coming towards you. You are totally illuminated and become light. Stay like this for a long time, as long as you can, then send light to others—to your father and all beings. Do this several times a day and carry on until he recovers.
Another thing you can do for him is Medicine Buddha Puja. Visualize Medicine Buddha above his head filling him with nectar.
With much love and prayers...
