A BODHISATTVA IS an ordinary person who takes up a course in his or her life that moves in the direction of buddha. You're a bodhisattva, I'm a bodhisattva; actually, anyone who directs their attention, their life, to practicing the way of life of a buddha is a bodhisattva. We read about Kannon Bosatsu (Avalokiteshvara Bodhisattva) or Monju Bosatsu (Manjushri Bodhisattva), and these are great bodhisattvas, but we, too, have to have confidence or faith that we are also bodhisattvas.
The life that flows through each of us and through everything around us is actually all connected. To say that, of course, means that who I really am cannot be separated from all the things that surround me. Or, to put it another way, all sentient beings have their existence and live within my life. So needless to say, that includes even the fate of all mankind--that, too, lies within me. Therefore, just how mankind might truly live out its life becomes what I aim at as my direction. This aiming or living while moving in a certain direction is what is meant by vow. In other words, it is the motivation for living that is different for a bodhisattva. Ordinary people live thinking only about their own personal, narrow circumstances connected with their desires. In contrast to that, a bodhisattva, though undeniably still an ordinary human being like everyone else, lives by vow. Because of that, the significance of his or her life is not the same. For us as bodhisattvas, all aspects of life, including the fate of humanity itself, live within us. It is with this in mind that we work to discover and manifest the most vital and alive posture that we can take in living out our life.
