"Tantric Zen, at first, does not appear to have a method. In Tantric Zen, you could meditate on a Brillo box or you could meditate on the clear light of reality."

The plain wooden toothpick, it may be argued, is among the simplest of manufactured things. It consists of a single part, made of a single material, intended for a single purpose-from which it gets its simple name. It is also among the most convenient and ready of things. It can be used directly out of the box-there being no instructions to read, no parts to assemble, no priming or booting required, and no maintenance expected. When it has served its purpose, it is simply discarded.
