"When we are humble everyone is a potential best friend and our generosity naturally grows. We want to do things, to help out. A wonderful Zen tradition is called "inji-gyo," or secret good deeds. The virtue gained through performing a secret good deed is believed to be immense. So, in a monastery, if one watched closely, you might see a monk secretly mending another's robes or taking down someone's laundry and folding it before the rain comes. In our temple I often find chocolate spontaneously appearing in my mailbox, or a beautiful poem, unsigned. This year the Easter Bunny visited our Sunday service, leaving chocolate eggs under everyone's cushions, even the one prepared for a visiting Zen master. Sometimes the bathrooms are miraculously cleaned overnight. And flowers spontaneously appear in a neighbor's yard, thanks to the children in the temple. Secret good deeds. They are so much fun. In their doing you can't help but smile."
