A good stance and posture reflect a proper state of mind - Morihei Ueshiba

Transcendence belongs to the profane world. When all trace of transcendence vanishes, the true person — the divine being — is manifest. Empty yourself and let the divine function

True Budo is done for the sake of "building peace". Train every day so as to make peace between this spirit [Budo] and all things manifested on the face of the Earth. (p. 26)

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.
