Each and every word of Srimad-Bhagavatam, full of volumes of explanation, each and every word. This is Srimad-Bhagavatam. Vidya-bhagavatavadhi. One's learning will be understood when he's able to understand Srimad-Bhagavatam. Vidya. Vidya means learning, not this science, that science. When one can understand Srimad-Bhagavatam in true perspective, then he's to be understood that he has finished his all educational advancement. Avadhi. Avadhi means "this is the limit of education." Vidya-bhagavatavadhi.
