The greatest power is the power of love. The trainee has to endure until he or she is beyond everything. There is no limit to the ability to endure. Zen is the doctrine of contrasts, of clashing of oppositions. The foundation of Man is rooted in contradiction.
Human beings are creations of contradiction.
They are always bewildered, uncertain about the future. The seed of contradiction is deeply implanted. If we understand the essence of Zen by practice, body and mind are united, and we can solve our problems. Every human being must solve his deep problems individually and independently. Life and death are the vehicles of Enlightenment.
