You may be curious about someone wearing black sash and others didn't, though both showed similar martial prowess. The Master was approached, and the questions presented to him. His answer was lucid. "What is a black sash? By now you know that it means entry into discipleship, one who has proven himself over a period of rigorous training. He is dedicated, loyal, knowledgeable and above all, trustworthy. So trustworthy, in fact, that they alone in the organization have a rank which automatically expires annually unless they prove they are still worthy. "It is not an automatic award; there are no specific physical requirements to meet for all. The number of forms is irrelevant. Intangible elements are the most important elements in this promotion. Taking responsibility for one's life and actions, the ability to respect a trust; the ability to be friend, counselor, sibling, or training companion. "They do more than what is asked of them, seeing tasks not as duties but as challenges to learn from. They sacrifice time and effort. Rather than neglect work or school, they learn to cultivate each with their Kung Fu. They are competent in their chosen field, and use this knowledge to enhance that competence. They do not forget the philosophical principles after each class; they LIVE them. And they persevere, even--ESPECIALLY--when things get rough. "They lead, not through intimidation or rank, but through compassion and respect. They are models, and people openly and genuinely respect them. And they learn, always." The student pondered this answer for some time. He watched the senior students and new disciples work out, then he watched them during non-training time. In time he saw the difference in action between those who acted in full knowledge of their actions, and those desperately fighting a flow.
