Quote: “St. Teresa of Avila stated that this work of Venerable Louis converted over 1,000,000 souls in her day. She, along with St. John of the Cross, St. Francis de Sales, St. Charles Borromeo, St. Vincent de Paul, and St. Rose of Lima, all counted it among their favorite spiritual books.”
This classical spiritual work (in Chapter 46) gives a balanced view of the different vocations in The Church within the context of The Mystical Body of Christ on earth, The Church - it is not a long chapter and beautifully written with simplicity and sound theology.

"Let us, then, beware of judging others because their virtues are not ours, or of expecting all to follow the same path. This would be destroying the body of the Church, rending the coat of Joseph. It would be exacting the duty of the eyes, or the hands, or the feet, from all the members of the body. In the words of the Apostle, if the whole body were the eye, where would be the hearing; or if it were the ear, where would be the eyes? Can the eyes reproach the feet for being blind, or the feet reproach the eyes for not bearing the burden of the body? No; it is necessary that the feet toil on the ground, and that the eyes be above them, protected from all that could fatigue or sully them. Nor is the duty of the eyes, notwithstanding their repose, less important than that of the feet.
The work of the pilot who stands at the helm is no less necessary than that of the sailors who manage the ropes and sails. We must not judge of an action by the labor it requires, but by its value and the effects it produces. Thus, you would not say that the work of a laborer is more important in a commonwealth than that of the statesman who wisely directs the government.
If we seriously weigh these considerations, we shall learn to respect all vocations. We shall not reproach the hand for not being the foot, nor the foot for not being the hand. We shall understand the truth of the Apostle’s words when he tells us that the beauty and perfection of the body result from the diversity of its members"
I think that the book is still available (unsure) but there is a full online copy on EWTN. The different Chapters in the book can be found here: ewtn.com/library/SPIRIT/GRANADA.HTM
