I’m happy to see that you esteem the teachings of St. John of the Cross, R_C.
It would be helpful to review
this entire chapter then, because it restates what I had been trying to say previously.
3. the good that overflows in the soul from supernatural apprehensions, when they come from a good source, is produced passively in the soul at that very instant when they are represented to the senses, without the working of any operation of the faculties.
Wherefore it is unnecessary for the will to perform the act of receiving them; …] Nay, rather, as the spirituality coming from those imaginary apprehensions is given passively to the soul, even so must the soul conduct itself passively with respect to them, setting no store by its inward or outward actions. To do this is to preserve the feelings that have their source in God, for in this way they are not lost through the soul’s base manner of working.
He is not suggesting we treat these as an enemy, but to remain passive concerning them. But here is the really important part, where we are not to set them aside passively, but to actually recall them.
And in this case the soul will make account, not of feelings of sweetness or delight, nor of figures, but of the feelings of love which they cause it.
And with this sole end in view it may at times recall that image and apprehension caused it by love, in order to set the spirit on its course of love.
For, though the effect of that apprehension be not so great afterwards, when it is recalled, as it was on the first occasion when it was communicated, yet, when it is recalled, love is renewed, and the mind is lifted up to God, especially when the recollection is of certain figures, images or feelings which are supernatural, and are wont to be sealed and imprinted upon the soul in such a way that they continue for a long time – some of them, indeed, never leave the soul.
And those that are thus sealed upon the soul produce in it Divine effects of love, sweetness, light and so forth, on almost every occasion when the soul returns to them, sometimes more so and sometimes less;** for it was to this end that they were impressed upon it. And thus this is a great favour for the soul on which God bestows it, for it is as though it had within itself a mine of blessings.**
I realize, since you said you had not read all of the Ascent, you may not have come to this chapter yet, for it is at the end, Book III.

It is late, or I would try to share what St. Teresa said, as well.
God bless you.
