What are the cardial rules in martial arts?

Answer 1

Iin the real world of self protection the most sacred rule is "there are no rules".

Martial Arts can mean many thing to many people. However to be effective in survival one must not expect or consider giving any tolerance to chance.

The only principle universal to all martial arts, according to Aikido's founder Morihei Ueshiba ("O'Sensei"), while he did not put it in these words, he stated that, ultimately, all martial arts are a sad, tragic waste of time.

Each martial art has it's own rules and specifications from "Anything Goes" to very strict guidelines on where, when and how a person can strike. For the most part they deal with being safe and not causing problems.
