I prefer to use reading as an example. Most people see the second layer, which is what Wang Yangming said: the ears hear and the mouth speaks, but the mind has nothing. Outstanding individuals can see the third and fourth layers, where the knowledge truly enters the mind and has a real impact on life practice; this is the meaning of reading. Exceptional individuals can see the fifth layer, aspiring to be like the virtuous, recognizing the gap between themselves and the author, and continuously striving to close that gap through reflection and practice.
