Hey Bill,
I understand what you are talking about. Its almost like a mindlessness, where your body moves the instant you anticipate. Almost like "sensitivity" training, where you're not sure if it is touch or thought that triggers your movement. No active thought, just a sense of being and time and movement.
Naaa, not what I mean.
Dragon style, when we train our Ying Jau Lin Que which was (and I am repeating myself, I apologise) taught to Si Gung from Lam Yeu Gwai, we use a different "energy". Dragon power, a full body, comprehensive, overwhelming committment. Not an anger, but a possession of fearsome power. More like a God than a mortal.
Pak Mei forms have more of a rage, a destructive, merciless committment. I find the Dragon energy more aloof whereas I find the Pak Mei energy more demonic, closer to evil. There is no mercy.
Maybe the difference between Tiger and Dragon energy if you play 5 animals lore?
Of course, I could simply be my own neurotic skirts showing....I'd be really keen to hear from some other Loong Ying Players
