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.
Miyamoto MusashiIf you learn indoor techniques, you will think narrowly and forget the true Way. Thus you will have difficulty in actual encounters.
Miyamoto MusashiWhen your spirit is not in the least clouded, when the clouds of bewilderment clear away, there is the true void.
Miyamoto Musashi
