No. All my training and teaching is based on instinct. That coupled with the training gives you fluidity in your movement and the ability to move seamlessly between techniques. The more you train this way the softer you become as you can't move quickly if your body is tense. Soft Ki takes the training to another level. In a street fight what you see is hard Ki. It manifests in aggression, power and strength. Most street fights you see are guys clashing violently with each other. Almost invariably, one succumbs to the more aggressive or stronger person. At that time I would suggest the loser has lost his Ki and hence his ability, or will, to continue. You can define Ki as you like .. mind, spirit, will, intent, whatever. When the mind and body are together we are strong. Take away the will to resist and you fall in a heap.
