Srimad-Bhagavatam, each line, each word is so much impregnated with philosophical thoughts that you can study one word throughout your whole life — it is so philosophical. It is not a professional business, that you finish Bhagavata within one week. One life is not sufficient to understand one word of Bhagavata, it is so big philosophical thing. But it has become a profession, Bhagavata-saptaha. What you will understand within one week, the whole Bhagavata? One word requires explanation one life.
