The heart of a human being is no different from the soul of heaven and earth. In your practice always keep in your thoughts the interaction of heaven and earth, water and fire, yin and yang.
Morihei UeshibaIn your training, do not be in a hurry, for it takes a minimum of ten years to master the basics and advance to the first rung. Never think of yourself as an all-knowing, perfected master; you must continue to train daily with your friends and students and progress together in the Art of Peace.
Morihei Ueshiba
