Since Jiu-Jitsu is Art, it isn’t any one thing.
Along such lines, trying to condense Jiu-Jitsu into any one idea closes the mind.
To illustrate what are the limitations/drawbacks of each of the following statements?:
Jiu-Jitsu is the Survival Art.
Jiu-Jitsu is the Efficient Art.
Jiu-Jitsu is the Gentle Art.
Jiu-Jitsu is the Art Without Limits.
Remember, education is about better questions, not answers.
