The outgoing intuitive capacity of mind; its model in the physiological is the creation of life by means of the harmonious integration of the yin and yang. It rests upon the state of selflessness.

誠実（せいじつ） / good faith, sincerity, faithfulness, honesty, fidelity, honest, faithful, truthful, sincere
誠心誠意（せいしんせいい） / wholeheartedly, devotedly, faithfully, from the bottom of one's heart
誠に（まことに） / really, truly, indeed, very, much, greatly, sincerely
誠を尽くす（まことをつくす） / do in good faith

When speaking of integration of yin and yang we have to speak in both literal and spiritual aspects pulling both together into one whole-heart view, perception and understanding. Shinto is wa and wa is harmony in all things.

Heaven, man and Earth - harmonious balance that connects and brings enlightenment in the actions, deeds and thoughts of humanity. The universe encompasses many systems including ours as if they were separate persons while our solar system is but one of many. The sun can be equated to the heart of man while the moon can be the hara where the sun provides a solar energy and the hara influences the Earth as man's hara influences his being.

Only by a cohesion of all parts into a whole integrated and harmonious one can the way be followed to the betterment of the person, the dojo and society or humanity as a whole.
