Since all the narrations of Śrīmad-Bhāgavatam bring the reader to the perfection of transcendental knowledge, they all give supreme spiritual lessons though apparently dealing with kings or other mundane subject matter. In relation with Kṛṣṇa, all ordinary topics become transcendental narrations, with the power to bring the reader to the perfection of life.
