When I pick up a book or open a door, I want to invest myself in this act 100 percent. This is what I learned during my monastic training, when my teacher taught me how to offer a stick of incense. A stick of incense is very small and very light, yet the right way to hold it is with two hands. When offering the incense, you have to invest 100 percent of your being in your hands and in two of your fingers—the energy of mindfulness must be concentrated there. This may look like a ritual, but it is a really an act of concentrated awareness. I put my left hand on my right hand, and during this time, I concentrate 100 percent. The incense is an offering to the Buddha, but does the Buddha really need incense? This is actually an offering of peace, of joy, and of concentration.
