Psychological emotions that arise without any cause all belong to the manas

Whenever the mind consciousness worries, fears, or feels depressed for no apparent reason, it all comes from the manas. Because there is no apparent reason, the mind consciousness does not know why the manas has these emotions, yet it can know the mind consciousness's own reasons. The emotions vented by the mind consciousness all have causes, because the mind consciousness can introspect, analyze, and deliberate, and thus knows why it itself loses its temper and has emotions; but it is not easy to observe and analyze the emotions of the manas.

When the mind consciousness cannot analyze or deliberate yet still loses its temper or feels depressed, that all comes from the manas—it is the manas that directs the mind consciousness to vent emotions. For example, upon waking in the morning, before coming into contact with anything, one inexplicably feels unwell, feels distressed, and wants to lose one's temper—all of that comes from the thoughts and emotions of the manas. The mind consciousness does not know what the manas is thinking, but the manas will inevitably impel the mind consciousness to vent these thoughts and emotions.

Many emotions that cannot be explained or made clear for a time all come from the manas; even emotions that the mind consciousness keeps trying to control but cannot control all come from the manas. By observing from this angle, one can gradually distinguish between the mind consciousness and the manas. If the mind consciousness knows that something is not good and feels somewhat worried, but the mind consciousness then rationally analyzes and concludes that it is nothing, yet the mind still keeps worrying, or worries more and more—what is going on here? This is that the manas has become worried. The mind consciousness says it is nothing, but the manas does not accept it, does not understand, and so will continue to worry incessantly.
