From September 5th (Friday) to 7th (Sunday), a 3-day, 2-night 'Internal and External Qi Intensive Training Retreat' was held at the Balgeul Meditation Center. In this retreat, both internal and external practices were addressed; in the internal training, breath training was deepened, and in the external training, participants systematically learned martial arts and swordsmanship. In particular, participants were able to verify and improve their training status through direct breath inspection and guidance from Zen Master Jinmok. During the external training hours, there was a focused practice of martial arts and sword techniques, allowing participants to experience the application of the energy cultivated in internal training within actual movements.The next intensive training is scheduled for November.
