NIN - important symbolism behind the To-Shin name
The Japanese written character for nin (pronounced "neen"), of Japan's
legendary ninja warriors and their martial art of ninjutsu, indicates endurance,
perseverance, and the ability to overcome obstacles.
The top portion of the Japanese character for nin is pronounced "toh" and means "sword". This represents the martial arts technology we study to perfect. The bottom portion of the character is shin, pronounced "sheen", and means "heart". This represents the resolute spirit needed to prevail over negative forces attempting to drive us to failure.
We know what we need in our lives and we take positive action to bring it into being. Nin communicates the kind of inner strength that is required to keep our eyes on the grander goal. We are not diverted, even when tempted by those persons or events that would try to pull us from our noble quest of personal improvement.
