Fudo-Shin is the state of enlightenment after
successful and complete devotion and application of Karate-Do: the way;
the state of balance and completeness. It is an unattainable goal and a way of continual improvement.
external : stability (static), balance (dynamic), force (power)
internal : concentration of energies (focus of will)
Shin : signifies spirit (soul)
Fudo-Shin, as guiding principle, defines the higher meaning of martial arts.
Which way to choose to attain Fudo-Shin is less important than the devotion to
reach it. Just be careful to keep your goal in mind, and your mind on the goal.
