Excerpt from <span class="chinese-post-title">樁法換勁</span> Training the Sinews and Bones in <span class="chinese-post-title">意拳正軌</span> The Correct Path of Yiquan

所謂身有平準，腰似車輪，氣如火葯拳如彈，靈機微動鳥難騰，更以心小膽大，面善心惡，靜似書生，動若龍虎，總以虛實無定，變化無蹤為準則，自能得其神妙之變化，故郭雲深大法師常云：有形有意都是假，技到無心始見奇，蓋即指此也。

王薌齋

"It is said: “The body is like scale, the waist like a wheel, the energy like gunpowder, the fists like bullets. The spirit acts with such subtlety, a bird could not escape.” Furthermore, let your thoughts shrink and your courage enlarge. Have a benevolent countenance but a ruthless mentality. Be in stillness like a scholar, in motion like a dragon or tiger.
Always the standards should be:
– Let emptiness and fullness be unfixed.
– Adapt, but without complying.
Then naturally you will be able to obtain the art’s ingenuity of transformation. Grandmaster Guo Yunshen often said: “To have a ‘shape’ or ‘intention’ is in either case a contrivance. Once your skill attains the level of unconscious action [‘no mind’], then you will notice wonders.” His words indicate these standards.”"
