Shantideva Prayer

May I become at all times, both now and forever
A protector of those without protection
A guide for those who have lost their way
A ship for those with oceans to cross
A bridge for those with rivers to cross
A sanctuary for those in danger
A lamp for those without light
A place of refuge for those who lack shelter
And a servant to all in need
For as long as space endures,
And for as long as living beings remain,
Until then may I, too, abide
To dispel the misery of the world.

Shantideva was an 8th century Indian Buddhist monk. There are many forms of this prayer, attributed to him.
