Staying On The Path God Has Chosen
If a fowler goes straight to a partridge’s nest, the bird will show herself to him and pretend to be weak and lame. She will rise up as if to make a great flight and then fall down all of a sudden as though unable to go any further. All this is done so that the hunter will keep after her, think he can catch her easily, and thus be distracted from finding her little ones outside the nest. When he has chased her for a while and fancies he has caught her, she takes to the air and escapes.
Thus too, when our enemy sees a man who by God’s inspiration undertakes a profession and way of life suitable to his advancement in heavenly love he persuades him to take some other path, apparently of greater perfection. Having once lured the man from his first path, little by little he makes it impossible for him to follow the second. Next he proposes a third way to the man. All this is so that by busying himself with a continual search for different new ways to perfect himself, he is kept from using any and consequently from arriving at the end which he seeks them―namely, perfection.
