Intellect, Will and Emotions (emphasis added)

From St Faustina III:1103

The quintessence of love is sacrifice and suffering. Truth wears a crown of thorns. Prayer involves the intellect, the will, and the emotions.

III: 1152

It is no easy thing to bear sufferings joyfully, especially those which are unmerited. Fallen nature rebels, and although the intellect and will are above suffering, because they are able to do good to those who inflict suffering on them, nevertheless the emotions raise a lot of noise and, like restless spirits, attack the intellect and will. But when they see they cannot do anything by themselves, they quiet down and submit to the intellect and will. Like some kind of hideousness, they rush in  and stir up a row, bent on making one obey them alone so long as they are not curbed by the intellect and will.
