This reminds me of a story I read in Black Belt Magazine 20 years ago;
A new person joined an Aikido dojo, excited about studying a true spiritual way through the martial arts. He saw all the whirling hakama and wanted to know it's significance.
A senior student explained, that through the hakama, she had learned precognition and extreme patience.
The newbie, hearing this, got real excited. In what does the power of the hakama lie? Is it in the folds? In a secret way to tie it?
The senior student explained, "The hakama is such a pain to take on and off, you learn how to tell if you're gonna have to go to the bathroom in the next few hours. And until you learn that, you learn to hold it until the end of class."
