“I will go over mountains and strands.”
5. Mountains, which are lofty, signify virtues, partly on account of their height and partly on account of the toil and labor of ascending them; the soul says it will ascend to them in the practice of the contemplative life. Strands, which are low, signify mortifications, penances, and the spiritual exercises, and the soul will add to the active life that of contemplation; for both are necessary in seeking after God and in acquiring virtue. The soul says, in effect, “In searching after my Beloved I will practice great virtue, and abase myself by lowly mortifications and acts of humility, for the way to seek God is to do good works in Him, and to mortify the evil in ourselves, as it is said in the words that follow:
“I will gather no flowers.”
6. He that will seek after God must have his heart detached, resolute, and free from all evils, and from all goods which are not simply God; that is the meaning of these words. The words that follow describe the liberty and courage which the soul must possess in searching after God. Here it declares that it will gather no flowers by the way—the flowers are all the delights, satisfactions, and pleasures which this life offers, and which, if the soul sought or accepted, would hinder it on the road.
7. These flowers are of three kinds—temporal, sensual, and spiritual. All of them occupy the heart, and stand in the way of the spiritual detachment required in the way of Christ, if we regard them or rest in them. The soul, therefore, says, that it will not stop to gather any of them, that it may seek after God. It seems to say, I will not set my heart upon riches or the goods of this world; I will not indulge in the satisfactions and ease of the flesh, neither will I consult the taste and comforts of my spirit, in order that nothing may detain me in my search after my Love on the toilsome mountains of virtue. This means that it accepts the counsel of the prophet David to those who travel on this road: “If riches abound, set not your heart upon them,” This is applicable to sensual satisfactions, as well as to temporal goods and spiritual consolations.
8. From this we learn that not only temporal goods and bodily pleasures hinder us on the road to God, but spiritual delight and consolations also, if we attach ourselves to them or seek them; for these things are hindrances on the way of the cross of Christ, the Bridegroom. He, therefore, that will go onwards must not only not stop to gather flowers, but must also have the courage and resolution to say as follows: “I will fear no wild beasts and I will go over the mighty and the frontiers.”
