Doka.  Poems of the Way.  Didactic verses of instruction used by a master (O Sensei) to express his or her teachings.

The Art of Peace begins with you. Work on yourself and your appointed task in the Art of Peace. Everyone has a spirit that can be refined, a body that can be trained in some manner, a suitable path to follow. You are here for no other purpose than to realize your inner divinity and manifest your innate enlightenment. Foster peace in your own life and then apply the Art to all that you encounter.

(O Sensei)

In your training, do not be in a hurry, for it takes a minimum of 10 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.

(O Sensei)
