In holding your antagonist, therefore, you should hold him lightly as if your arms were nothing but chains which connect you with him, so that you may stretch or contract them at will when necessary, and pull or push him in any direction you choose. If you pull your opponent or apply your tricks on him by putting from the beginning too much strength in your arms, then you are going to contest with him by means of your power and against the principles of Judo. In doing so, you can never expect to succeed in your contest.
Yokoyama SakujiroThe Judo pupil, therefore, must cultivate his mind; he must never feel fear, never lose his temper, never be off his guard; but he must be cool and calm, though not absent-minded; he must act as quick as thought, according to circumstances. He must also be dexterous as well as bold both in attack and in defense.
