In Zen, we live by vow. We follow a 2500-year-old value system that appears through actualization. This is not just being values-oriented, but by actualizing values day-by-day-by-moment. This must be our "Way" if we are Bodhisattvas. "Our Way" is what Shakyamuni Buddha actualized.

Zen is being thorough in the moment.
