When we bring together the ancient spiritual traditions of East and West, we find a meeting point where the warrior tradition can be experienced and realized. The concept of being a warrior is applicable to the most basic situations in our lives—to the fundamental situation that exists before the notion of good or bad ever occurs. The terms warrior relates to the basic situation of being a human being. The heart of the warrior is this basic aliveness or basic goodness. Such fearless goodness is free from doubt.
