6.134

The Commentary states: This master's intention states that when these five—desire and so forth—arise, if one arises, the other four are necessarily present. Only when mutually assisting one another does their operation occur, so the five must arise together. If one does not arise, none of the other four arises; this is the view of Sthiramati. In the West, they collectively questioned this treatise, saying: 'Treatises say that four objects are able to generate desire and so forth; how could these five definitely arise together? Furthermore, if there is an object that has not been previously experienced, and merely hearing of its supreme renown gives rise to longing desire, how could there be mindfulness? Because there is no concentrated focus, how could there be concentration? Since one does not determine whether it is right or wrong, there is also no resolve; therefore they definitely cannot be concurrent.' That master replies that the four objects generating desire and so forth is spoken in terms of the predominance of the mental modes of the five, desire and so forth; that is, desire is merely predominant regarding an agreeable object, so it is spoken of specifically, but it is not that the subtle forms of the other four are truly absent therein, hence they must mutually assist each other.
