The Spirit of OSU
Osu is made up of two kanji, "o" meaning to "push" which symbolizes one hundred percent effort and "su" means to "endure". Combined, "osu" is a pledge to do one's best and endure. The martial arts require a great deal of discipline which involves a great deal of self-reflection, and self-reflection is more concerned with irrefutable truths than with rewards. Osu means patience, respect and appreciation. In order to develop a strong body and strong spirit it is necessary to undergo rigorous training.
This is very demanding, because you must push yourself to what you believe to be your limit, and you want to stop; to give up. When you reach this point you must fight yourself and your weakness and you must win. To do this you must learn to persevere whilst being pushed, but above all you must learn to be patient.
This is OSU!
