The fact that the book was meant for the novice is clear from the prefatory paragraphs that precede the discourses. The twenty four discourses are selected from the five Nikayas or the original Collections in Pali containing the Buddha's discourses.

The idea was that those novices who are not capable of studying large portions of the "Discourse Collection" (sutta pitaka) should at least be conversant with the Book of Protection. The Book of Protection which is an anthology of selected discourses of the Buddha compiled by the teachers of old, was originally meant as a handbook for the newly ordained novice.
