The intellect receives impassioned conceptual images in three ways: through the senses, through the body's condition and through the memory. It receives them through the senses when the senses themselves receive impressions from things in relation to which we have acquired passion and when these things stir up impassioned thoughts through the intellect; through the body's condition when, as a result either of an undisciplined way of life, or of the activity of demons, or of some illness, the balance of elements in the the body is disturbed and again the intellect is stirred to impassioned thought or to thoughts contrary to providence; through the memory when the memory recalls the conceptual images of things in relation to which we were once made passionate, and so stirs up impassioned thoughts in a similar way. (Maximos the Confessor)

And is this bad?

If the conceptual images spawned by our senses, our condition, or our memory prompt anger, lust, avarice, gluttony or other actions to diminish or endanger a healthy relationship with God, neighbor, or self, then such conceptual images are at least distracting and potentially much worse.

But conceptual images can also inspire, encourage, and remind us of what has been, or is, or can be beautiful, good, and true.

I do not hear Jesus in any way advocating dispassion. But I certainly hear encouraging a mindful and meaningful choice of passions.
