At the beginning and end of each class the Ninniku Seishin or spiritual code of the Ninja is chanted in Japanese to align the heart with heaven.
The spirit of the Ninja; Body, Mind and Conscience as one enduring all.
This is the principle of the forbearing spirit.
First bear all humiliation, denounce ill will and resentment, raising the spirit to acquire the virtue of patience.
Take not the meaning of Nin to be the blade before the heart, but learning that the heart of the flower, is one of peace and harmony, and like love and affection there is happiness in peace.
The miracle of Truth and Falsehood in diversionary tactics.
Earth, Water, Fire, Wind, and Air, to subdue one's opponent.
This philosophy being the essence of the ninja spirit (Ninniku seishin).
