Think more, talk less.

Everyone should sharpen their own mind more and exercise their lips less. Using the brain is far better than using the mouth, because only with a powerful mind can one obtain wisdom and merit. The function of the brain is primarily that of the manas, while the lips are the skill of the mind consciousness—which function is stronger and more capable of solving problems? Thinking hard is exhausting, while moving the lips takes no effort, so many people do not use their brains and only move their lips—but what problems can moving the lips solve? Those with profound deliberation speak little, while those who talk much think shallowly. One relies heavily on the manas, the other relies heavily on the mind consciousness. Such is the relationship between the manas and the mind consciousness: as one wanes, the other waxes—one is deep, the other shallow. Is it better to be deep or shallow?
