SHIN (KOKORO)

It’s the Heart, the spirit, and "soul" of a person or a thing. According to the Chinese and Japanese concept, the center of the spirit is not in the head (where only the intellect resides), but in the heart. Shin represents therefore the essence of the human being (or thing), its absolute reality, in an art, martial or another type, a disciple could not prevail if the artist is not in the Shin (spirit) said of another way, if the practitioner does not have the sacred fire and "does not work with desire" The-Kokoro is therefore "the dispassionate" passion, that is to say, the action without benefit desire.

A Budoka that after a beautiful combat has been defeated does not have to become sad but rather be glad, because this defeat, well understood, could contribute to his or her own education.

Having fought, not to win at all costs, but to overcome himself and himself only, is then said to have that spirit, which is the a essence of pure love.
