... the Lord fills His teachers with grace according to the quality and longing of those who listen.
("Philokalia (Vol. 1)", p. 98)
Most people, however, without exerting any effort or making any real progress, small or great, in the practice of virtue, simply chase after the status of spiritual director, not realizing how dangerous this is... Spiritual directors of this kind like to appear in public supported by a large crowd of attendants, and to have all the outward pomp of an abbot, as if playing a part on the stage. So as not to lose the services of their disciples, they are forced to keep on gratifying their whims. They are like a charioteer who drops the reins and lets his horses go where they like. Their disciples are allowed to run wild: carried away by their desires, they fall over precipices or stumble at every obstacle in their path, because there is no one to stop them or to restrain their disordered impulses.
("Philokalia (Vol. 1)", pp. 222-223)
Experience shows that the task of guiding others should be undertaken by someone who is equable and has no personal advantage in view.
