Canticles 2:6

3. You ought, then, to be informed in the first place, and, those of you who can, to understand, and the others, who cannot as yet understand, to believe, that in that substantial essence, which is God, the senses are not, as if through some material structure of a body, distributed in their appropriate places; as, in the mortal flesh of all animals there is in one place sight, in another hearing, in another taste, in another smelling, and over the whole the sense of touch. Far be it from us to believe so in the case of that incorporeal and immutable nature. In it, therefore, hearing and seeing are one and the same thing. …

Some people may be eunuchs from necessity; I am one of free will. “There is a time to embrace and a time to refrain from embracing. There is a time to cast away stones, and a time to gather stones together.” Now that out of the hard stones of the Gentiles God has raised up children unto Abraham, they begin to be “holy stones rolling upon the earth.” They pass through the whirlwinds of the world, and roll on in God’s chariot on rapid wheels. Let those stitch coats to themselves who have lost the coat woven from the top throughout; who delight in the cries of infants which, as soon as they see the light, lament that they are born. In paradise Eve was a virgin, and it was only after the coats of skins that she began her married life. Now paradise is your home too. …

Those are they then who are figuratively spoken of in holy Scripture as ἀμφοτεροδέξιον , i.e., ambidextrous, as Ehud is described in the book of Judges “who used either hand as the right hand.” And this power we also can spiritually acquire, if by making a right and proper use of those things which are fortunate, and which seem to be “on the right hand,” as well as of those which are unfortunate and as we call it “on the left hand,” we make them both belong to the right side, so that whatever turns up proves in our case, to use the words of the Apostle, “the armour of righteousness.” For we see that the inner man consists of two parts, and if I may be allowed the expression, two hands, nor can any of the saints do without that which we call the left hand: but by means of it the perfection of virtue is shown, where a man by skilful use can turn both hands into right hands. …

( Admonition 27.) Differently to be admonished are those who prosper in what they desire in temporal matters, and those who covet indeed the things that are of this world, but yet are wearied with the labour of adversity. For those who prosper in what they desire in temporal matters are to be admonished, when all things answer to their wishes, lest, through fixing their heart on what is given, they neglect to seek the giver; lest they love their pilgrimage instead of their country; lest they turn the supplies for their journey into hindrances to their arrival at its end; lest, delighted with the light of the moon by night, they shrink from beholding the clearness of the sun. …
