Inexplicable anger belongs to the manas

When one becomes angry, the mind continuously tries to control one's emotions. The mind consciousness may control it for an hour, yet the manas still remains uncontrolled—this shows that the manas is indeed not easy to regulate. Very often, after anger arises, one does not even know why one became angry; and after being angry, one still does not know why. In that case, it is not the mind consciousness that is angry on its own, for the anger of the mind consciousness can always be traced to a cause and a reason. As for the anger of the manas, the mind consciousness cannot understand it; the mind consciousness thinks that the anger arises without any cause, and because it does not know why, it assumes it is groundless. In fact, the cause of the manas's anger is beyond the mind consciousness's knowing; unable to accurately grasp the mental activities of the manas, the mind consciousness is ignorant of it, and regards all of the manas's emotions as inexplicable and unreasonable. Only when the mind consciousness gives rise to great wisdom and comes to understand the characteristics of the manas can it master the mental states of the manas and subdue the afflictions of the manas.
