Even if you strive diligently on your chosen path day after day, if your heart is not in accord with it, then even if you think you are on a good path, from the point of view of the straight and true, this is not a genuine path.

There is no one way to salvation, whatever the manner in which a man may proceed. All forms and variations are governed by the eternal intelligence of the Universe that enables a man to approach perfection. It may be in the arts of music and painting or it may be in commerce, law, or medicine. It may be in the study of war or the study of peace. Each is as important as any other. Spiritual enlightenment through religious meditation such as Zen or in any other way is as viable and functional as any "Way."... A person should study as they see fit.
