"6. As a result the perfect spirit pays no attention to the senses. It neither receives anything through them, nor uses them principally, nor judges them to be requisite in its relationship with God, as it did before its spiritual growth. A passage from St. Paul's epistle to the Corinthians bears this meaning: Cum essem parvulus, loquebar ut parvulus, sapiebam ut parvulus, cogitabam ut parvulus. Quando autem factus sum vir, evacuavi quae erant parvuli (When I was a child, I spoke as a child, I knew as a child, I thought as a child. But when I became a man, I put away childish things) [1 Cor. 13: 11]. We have already explained how sensible things and the knowledge the spirit can abstract from them are the work of a child. Those who are always attached to them, and never become detached, will never stop being like a little child, or speaking of God as a child, or knowing and thinking of God as a child. In their attachment to the rind of sense (the child), they will never reach the substance of spirit (the perfect person). For the sake of their own spiritual growth, therefore, persons should not admit these revelations, even though God is the author of them, just as a child must be weaned in order to accustom its palate to a hardier and more substantial diet."
Juan de la Cruz
"5. Many blessings flow when the four natural passions (joy, hope, fear, and sorrow) are in harmony and at peace. The following maxims contain a complete method for mortifying and pacifying them. If put into practice these maxims will give rise to abundant merit and great virtues. 6. Endeavor to be inclined always: not to the easiest, but to the most difficult; not to the most delightful, but to the most distasteful; not to the most gratifying, but to the less pleasant; not to what means rest for you, but to hard work; not to the consoling, but to the unconsoling; not to the most, but to the least; not to the highest and most precious, but to the lowest and most despised; not to wanting something, but to wanting nothing. Do not go about looking for the best of temporal things, but for the worst, and, for Christ, desire to enter into complete nakedness, emptiness, and poverty in everything in the world.[ 3]"
