The mind consciousness serves the manas

If the manas wants to drink water, the six consciousnesses will come forth to boil the water, pour it, and brew tea, and then it is drunk into the mouth; if the manas does not want to drink water, the six consciousnesses will not come forth to do any of these things. The mind consciousness is never as important as the manas and can never be the master, because the mind consciousness is a dharma that is generated—it is the manas that decides whether or not it arises. It occupies a subordinate position, serving the manas, and moreover it must serve the manas well. If it does not serve well, the manas will feel uncomfortable and may even throw a tantrum. When the manas truly throws a tantrum, the mind consciousness sometimes feels utterly baffled. The mind consciousness is more rational than the manas, while the manas is far more prone to emotional reactions than the mind consciousness. If the manas wants to hear a certain sound, the mind consciousness must obey the manas's command and come forth to discriminate that sound. If the manas wants the six consciousnesses to appear, the six consciousnesses appear immediately; if the manas does not want the six consciousnesses to appear, the six consciousnesses will not appear; whatever the manas wants the six consciousnesses to do, the six consciousnesses must do accordingly.
