The essence of the martial arts and military strategies is self-protection and the prevention of danger. Ninjutsu epitomizes the fullest concept of self-protection through martial training in that it deals with the protection of not only the physical body, but the mind and spirit as well. The way of the Ninja is the way of enduring, surviving, and prevailing over all that would destroy one. More than merely delivering strikes and slashes, and deeper in significance than the simple outwitting of an enemy; Ninjutsu is the way off attaining that which we need while making the world a better place.
The skill of the Ninja is the art of winning. In the beginning study of any combative art, proper motivation is crucial. Without the proper frame of mind, continuous exposure to fighting techniques can lead to ruin instead of self-development. But this fact is not different from any other beneficial practice in life carried to extremes.
The vast universe, beautiful in its coldly impersonal totality, contains all that we call good or bad, all the answers for all the paradoxes we see around us. By opening his eyes and his mind, the Ninja can responsively follow the subtle seasons and reasons of heaven, changing just as change is necessary, adapting always, so that in the end there is no such thing as a surprise for the Ninja (Banpen Fugyo).
The way to experience ultimate happiness is to let go of all worries and regrets, and to know that being happy is the most satisfying of life's feelings. Reflect back on all the progress in your life and allow the positive, creative and joyous thoughts to outshine and overwhelm any sorrow or grief that may linger in the recesses of your mind. Knowing that disease and disaster are natural parts of life is the key to overcoming adversity with a calm and happy spirit. Happiness is waiting there in front of you. Only you can decide whether or not you choose to experience it. Take this to heart.
