Bodling"He who in any way compares himself with his fellow ascetics or with the brethren who live with him is unaware that he deceives himself and treads a path alien to God. Either he does not know himself or he has deviated from the path that leads heavenwards. But by following this path in modesty of mind, those more spiritually advanced surmount the devil's ploys and, winged by dispassion and adorned with humility, they attain the heights of spiritual illumination."
