In this little book the writer has aimed to present, in brief and simple form, sound principles which may assist the young in deciding their future course of life. The subject of vocation, as it is called, has suffered much, during the last two or three centuries, at the hands of rigorist authors, who so hedged the approach to religious life with difficulties and restrictions, as to frighten or repel many aspiring hearts from it. Great stress was laid by these writers on the special interior attraction, by which God was supposed always to manifest His call, so that no one might legitimately enter the state of perfection, unless he felt this unmistakable impulse from within. And on the other hand, given this evidence of the Divine predilection, to disregard it was a sinful preferring of one's own will to God's, which, in all likelihood, would be attended with grave consequences for this world and the next. My Reverend Father: Your little book pleases me exceedingly. Its doctrine is very sound and set forth with wonderful clearness. It makes pleasant reading, and will interest the young of school age, and encourage them to make a generous choice of a state of life. In my opinion, a Flemish and French translation would also be profitable to our college students in Belgium. Devotedly yours in Our Lord and Mary Immaculate, A. Vermeersch.
