Ninniku Seishin (English)
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.
Consequentially, one's body will naturally evade the opponent's sword, disappearing;
The miracle of Truth and Falsehood in diversionary tactics.
For one's Country, for Justice, using the elements of nature,
Earth, Water, Fire, Wind, and Air, to subdue one's opponent.
This philosophy being the essence of the ninja spirit (Ninniku seishin).
