(Crane vs. Tiger)

Principle – use circular and side movements against opponent’s straight attacks.

Principle – you should not limit yourself with strict form, instead you should act accordingly to situation (difference between kata and kumite).

Principle – if your stance is unbalanced (dachi) or movement of your hips is weak (koshi), then there is no focus (kime) and therefore your techniques do not have enough strength. This is in close relation with previous principle.

Principle – you should choose which technique to use carefully and according to situation. Do not use attractive techniques.

Principle – even if you use proper technique, which is according to situation, it is necessary to be calm and wise. If you do not control your strength then there is good chance to miss your target (fudoshin). This is in close relation with previous principle.

Principle – without “fighting spirit” knowledge is useless. Do not hesitate, when fight is started. Be serious and act confidently (zanshin).

Principle – use faints to defeat your opponent, because there are no rules in fighting.
