According to an ancient Jewish mystical legend the world will continue to exist as long as there are a minimum of thirty-six people who recognize the Divine Presence (Shekinah) in all things, and respond unconditionally with compassion to the suffering of others. They are called Lamed Vavs because the numerology for the Hebrew letters Lamed and Vav equals 36.

These Lamed Vavs are wellsprings of lovingkindness, pouring goodness and compassion upon the world. It is said that if at any time there are fewer than thirty-six such people, the world would implode under the weight of human greed, ignorance, selfishness, and anger.

The intriguing twist is that nobody knows who they are. They themselves don't even know. They are called "hidden saints"—hidden to themselves and to others. Some say they need not be the same thirty-six people at all times. You, me, any one of us, at any moment, might be one of these thirty-six upon whom the world depends. And so it calls us to act as though we are.
