May I be the doctor and the medicine
And may I be the nurse
For all sick beings in the world
Until everyone is healed.
May a rain of food and drink descend
To clear away the pain of thirst and hunger
And during the aeon of famine
May I myself change into food and drink.
May I become an inexhaustible treasure
For those who are poor and destitute;
May I turn into all things they could need
And may these be placed close beside them.
From The Way of the Bodhisattva, by Shantideva, Ch. III (trans. Stephen Batchelor)
