Bhagavan Sri Ramana Maharshi
If they don't serve any other purpose, the martial arts should serve as a vehicle for true transcendence. It's easy to conceive of this watching a lone practitioner performing his Taiji form in the park, or watching old Kung Fu TV series reruns. But once we begin the practice, we can easily become bogged down in the technical details or consumed with latent or blatant competitive drive and miss the forest for the trees. Sure, technical details are important but they shouldn't override the spirit. And spirit is both the easiest and the hardest aspect of our practice to realize. In essence it is always available, always with us. Yet, we have to acknowledge it and nurture it. The way to do that is to first destroy ego, then place your attention where you know it should be.
As O'Sensei said, "Heaven is right where you are standing, and that is the place to train." The technical details only give us the how-to of training. The rest is up to us.
