One of the most enduring and enjoyable experiences I have had with the energy of the Dragon Gate has been in a decades long study of the art of Shodo, or brush calligraphy. Here is an excellent description of the way that this energy is expressed through how the brush is held, from a book I highly recommend to anyone seriously interested in Calligraphy.
Quoted from Calligraphy and Power in Contemporary Chinese Society, by Yuehping Yen
"Force is important to Chinese calligraphy, but one should not begin to associate calligraphic skill with the size of a writer's arm muscles! Perhaps picking up an egg with chopsticks provides a useful analogy. What matters is not how much strength you impose on the egg, but at what angles the chopsticks touch the eggshell and how much force you apply to the chopsticks with each finger at those angles. In other words, it is the 'orchestration of forces', rather than the force as such, that occupies the central stage of the 'ballet of the brush' 6 (Mindich 1990). Enthusiasts of Chinese calligraphy are very likely to be familiar with an anecdote about a pair of father-and-son calligraphy gurus. When Wang Xianzhi (the son) was a small boy, Wang Xizhi (the father) once sneaked up to the son while he was practising calligraphy and tried to pull out the brush from his hand. But he failed. From this the father predicted that his son would be a distinguished calligrapher one day. Unfortunately, a false belief centering on this anecdote has been widely circulated since. The wrong message, deriving from reading the text too literally, is to equate the strength used to hold the brush with artistic excellence. If we look at the path which 'strength' must follow from its source, the calligrapher's body, to the surface of paper, we realize that it is not a straightforward path at all. On the way through the body to its final realization on paper, the force travels through many 'checkpoints' 7 - shoulder, elbow, wrist and knuckles. Through the fingers it finally meets the brush, and then the force passes through hundreds of hairs to meet the paper. At every checkpoint, the force can be passed on in one of many metamorphosed forms, depending on such factors as angle and time. Clearly, the intensity of force is far from the only determining factor. What really matters is the mastery of the co-ordination of all these factors that lie behind the simple-looking brush."
