In relationships between people, sincere communication is the genuineness of the manas, while falseness and perfunctoriness are the disguise of the mind consciousness. What is called tacit understanding refers to the coordinated cooperation between manas—without speaking, without expression, one glance and hearts connect. When two people's manas can cooperate tacitly, it shows that both of them are intelligent and that they understand each other. Conversely, no matter how the mind consciousness expresses and explains things with language, if the other person still does not understand, it shows that person is dull. Therefore, true intelligence and wisdom must refer to the manas; great wisdom, great courage, and great strategy must all refer to the manas. Only petty cleverness is the cleverness of the mind consciousness, which fails at critical moments.
Whether a person has great wisdom, with both high emotional intelligence and high intelligence, must refer to the manas, not the mind consciousness. The mind consciousness is all about scheming and stratagems, which cease to work when the environment and circumstances change, and especially fail at critical, life-and-death moments. Those of great wisdom generally speak little and prefer silence, for such is the depth and wordlessness of the manas; only those with petty cleverness like to show themselves off and play tricks and schemes, which corresponds to the mind consciousness.
