Mundane books are written by imperfect persons. Everyone has his own theory, which means he is imperfect. The Srimad-Bhagavatam says if there is a real presentation of spiritual understanding, then even if it is presented i broken language, it is accepted by high, saintly persons, because it glorifies the Supreme Person. On the other hand, if literature is highly metaphorically composed, if it does not glorify the Lord, it is compared to a place inhabited by the crows.

Actually, if some literature doesn’t carry any real knowledge, what is the use of ornamental language? We are not interested in presenting ornamental language.
