" Do not listen with your ears but listen with your heart; do not listen with your heart but listen with qi. . . . You have heard of using knowing to know; you have not heard of using not knowing to know. . . . Allow your ears and your eyes to penetrate on the inside, and place the understanding of the mind on the outside. "

― Michael Puett , Confucius, Mencius, Laozi, Zhuangzi, Xunzi: Selected Passages from the Chinese Philosophers in The Path
