《徐霞客游记·滇游日记四十六》
脚的力量一半寄托在手上，手的力量也是一半无所寄托，这是所谓的凭靠虚空驾御山风了，可实际上凭靠又无所凭靠，驾御也无所驾御。
足之力半寄于手，手之力亦半无所寄，所谓凭虚御风，而实凭无所凭，御无所御也。
Half of the strength of my feet is supported by my hands, and half of the strength of my hands is not supported by anything. This is what is called relying on the void to ride the mountain wind, but in reality there is nothing to rely on and nothing to ride.
