1. All knowledge is in Srimad-Bhagavatam

    In the Srimad-Bhagavatam you will find everything, whatever is necessity, for the advancement of human civilization. Everything is there described. And knowledge also, all departmental knowledge. Even astronomy, astrology, politics, sociology, atomic theory — everything is there. Vidya-bhagavatavadhi. Therefore if we study Srimad-Bhagavatam very carefully, then you  get all knowledge completely.
