Attaining supernatural transformation manifestly demands a darkening of the soul and an elevation above all the sensory and rational parts of nature, for the word “supernatural” indicates that which is above nature; nature, consequently, remains beneath… They will continually live as though denuded and darkened; they must lean on dark faith, accept it for their guide and light, and rest on nothing of what they understand, taste, feel, or imagine. All these perceptions are darkness and will ultimately lead them astray. Faith lies beyond all this understanding, taste, feeling, and imagining.
Saint John of the Cross
