In Zen we refer to taking refuge in the Three Jewels: the Buddha, the Dharma and the Sangha. Some thoughts from Zen Master Dae Gak:

"Looking at taking refuge as medicine: to take refuge in the Buddha means to acknowledge that what is most important is not the Buddha as the head of a religious organization but to take refuge in one's own capacity for enlightenment; I am Buddha." - Upright with Poise and Grace
