Here is an excerpt from my book, Seven Steps to Inner Power:
You may become keenly aware of your weakness and negative thoughts and emotions as you train in a martial art because you’re making greater demands on your body and asking yourself to perform in ways you previously considered impossible. But keep in mind, as we discussed in the section on Purity in chapter four, that your weaknesses are “shadows” of your real characteristics. The war against a shadow does not have to be waged with force. It’s not sensible to fight against something that’s insubstantial, is it?
Instead, the war can be won by gently embodying the real idea about yourself, whatever it may be at the time.
“Gently” doesn’t mean “weakly,” however. Gentleness is its own kind of force. Remember the fable about the contest between the Sun and the Wind? They each tested their power by attempting to make a man walking along a road take off his cloak. As the wind ripped and tore at the man with tremendous force, the man only drew the cloak tighter and tighter around him, until the Wind finally gave up and challenged the Sun. The Sun, however, showed no “force” at all; gently and persistently, it burned brighter and hotter, until the man released his hold on the cloak and took it off in the warmth of the day. This is the true nature of your conflict with yourself. Like the Sun, gently and persistently you must be who you are in truth.
Also during your warfare, remember what we discussed in the section on Truth in chapter four: To make your work easier, you must remain unimpressed with the evidence of your material senses. The material picture outside you is never the source of truth; it is a picture of what you’ve been believing to be true. Therefore, as a Jung SuWon warrior, you are not limited by any material evidence; you can change the picture when you change your thinking.
You are not limited.
