Drinking character and personal character are the quality of the manas

The state after drinking reflects the habits of the manas, revealing the manas as it originally is. After drinking, the brain nerves are anesthetized, the functioning of the five sense faculties is weakened, and the discriminating power of the six consciousnesses that arise is weakened. In this way, these six scouts can no longer accurately investigate the six sense objects, and the manas cuts off—or partially cuts off—the sources of information. The mind consciousness's role as advisor and assistant also becomes largely ineffective; its power of deliberation is weak, and its supervision, guidance, and oversight of the manas are feeble, so the manas acts according to its own nature. At this point, everything depends on the manas's own wisdom, and the manas's inherent nature and qualities are fully exposed. "In wine there is truth"—the words spoken after drinking are entirely the voice of that person's manas, the person's genuine thoughts, without the mind consciousness's concealment and pretense. What people commonly call "wine character" and "personal character" refers precisely to the qualities of the manas; this is a person's original face.
