‘I say, then, that since these imaginative apprehensions, visions, and other forms or species are presented through some image or particular idea, individuals should neither feed upon nor encumber themselves with them. And this is true whether these visions be false and diabolical or whether they be recognized as authentic and from God…The reason is that in being apprehended these forms are always represented in some limited mode or manner…Since God cannot be encompassed by any image, form or particular knowledge, the soul in order to be united with him should not be limited by any particular form or knowledge…To reach this essential union of love of God, a person must be careful not to lean upon imaginative visions, forms, figures or particular ideas, since they cannot serve as a proportionate and proximate means for such an effect…The only reason for admitting and valuing them would be the profit and good effect the genuine ones bring to the soul. But admitting them is unnecessary to obtain this good effect; for the sake of (spiritual) progress, rather, one should always deny them.’ - St John of the Cross
