Nisu stvari ovog svjeta te koje gospodare dušom i uništavaju je,jer one u nju ne ulaze,nego želja i čežnja za njima koje u njoj prebivaju. - John of the Cross

O spiritual soul, when thou seest thy desire obscured, thy will arid and constrained, and thy faculties incapable of any interior act, be not grieved at this, but look upon it rather as a great good, for God is delivering thee from thyself, taking the matter out of thy hands; for however strenuously thou mayest exert thyself, thou wilt never do anything so faultlessly, perfectly, and securely as now — because of the impurity and torpor of thy faculties — when God, taking thee by the hand, is guiding thee in the dark as one that is blind, along a road and to an end thou knowest

As for the vice of lust - aside from what it means for spiritual persons to fall into this vice, since my intent is to treat of the imperfections that have to be purged by means of the dark night - spiritual persons have numerous imperfections, many of which can be called spiritual lust, not because the lust is spiritual but because it proceeds from spiritual things. It happens frequently that in a person's spiritual exercises themselves, without the person being able to avoid it, impure movements will be experienced in the sensory part of the soul, and even
sometimes when the spirit is deep in prayer or when receiving the sacraments of Penance or the Eucharist. These impure feelings arise from any of three causes outside one's control.

First, they often proceed from the pleasure human nature finds in spiritual exercises. Since both the spiritual and the sensory part of the soul receive gratification from that refreshment, each part experiences delight according to its own nature and properties. The spirit, the superior part of the soul, experiences renewal and satisfaction in God; and the sense, the lower part, feels sensory gratification and delight because it is ignorant of how to get anything else, and hence takes whatever is nearest, which is the impure sensory satisfaction. It may happen that while a soul is with God in deep spiritual prayer, it will conversely passively experience sensual rebellions, movements, and acts in the senses, not without its own great displeasure.

This frequently happens at the time of Communion. Since the soul receives joy and gladness in this act of love - for the Lord grants the grace and gives himself for this reason - the sensory part also takes its share, as we said, according to its mode. Since, after all, these two parts form one individual, each one usually shares according to its mode in what the other receives. As the Philosopher says: Whatever is received, is received according to the mode of the receiver. Because in th

CHAPTER II Of certain spiritual imperfections which beginners have with respect to the habit of pride. AS these beginners feel themselves to be very fervent and diligent in spiritual things and devout exercises, from this prosperity (although it is true that holy things of their own nature cause humility) there often comes to them, through their imperfections, a certain kind of secret pride, whence they come to have some degree of satisfaction with their works and with themselves. And hence there comes to them likewise a certain desire, which is somewhat vain, and at times very vain, to speak of spiritual things in the presence of others, and sometimes even to teach such things rather than to learn them. They condemn others in their heart when they see that they have not the kind of devotion which they themselves desire; and sometimes they even say this in words, herein resembling the Pharisee, who boasted of himself, praising God for his own good works and despising the publican.
