The tenets of Taekwondo — Courtesy (Ye Ui), Integrity (Yom Chi), Perseverance (In Nae), Self-Control (Guk Gi), and Indomitable Spirit (Baekjul Boolgool) — are rooted in a blend of Korean martial arts philosophy, influenced by Confucian and Taoist thought, with modern interpretations. Historically, these principles were integrated into the practice of Taekwondo to develop not only physical prowess but also moral character, dating back to the mid-20th century when modern Taekwondo was formalized.
Courtesy involves showing respect to others, behaving with good manners, and recognizing the dignity of every individual. Integrity refers to a sense of honesty and justice, avoiding deceitful conduct, and living by a moral code. Perseverance embodies the spirit of unyielding pursuit of personal and martial excellence despite challenges. Self-control is about managing one's emotions and actions, particularly during conflict or competition. Indomitable Spirit speaks to the courage to stand for one's beliefs and to overcome adversity without losing one's principles.
From today's perspective, these tenets serve as a guide not only for martial arts practitioners but also for individuals seeking a disciplined and principled approach to life. They are considered timeless virtues that can contribute to personal development, leadership, and fostering a more respectful and resilient society. They underscore the importance of ethical behavior, mental fortitude, and the continuous pursuit of improvement in all areas of life.
