Śrīmad-Bhāgavatam is a personal commentation on the Vedanta-sutra by Srila Vyasadeva It was written in the maturity of his spiritual life through the mercy of Narada. Srila Vyasadeva is the authorized incarnation of Narayana, the Personality of Godhead. Therefore, there is no question as to his authority. He is the author of all other Vedic literatures, yet he recommends the study of Śrīmad-Bhāgavatam above all others. In other Puranas there are different methods set forth by which one can worship the demigods. But in the Bhāgavatam only the Supreme Lord is mentioned. The Supreme Lord is the total body, and the demigods are the different parts of that body. Consequently, by worshiping the Supreme Lord, one does not need to worship the demigods. The Supreme Lord becomes fixed in the heart of the devotee immediately. Lord Chaitanya Mahaprabhu has recommended the Śrīmad-Bhāgavatam as the spotless Purana and distinguishes it from all other Puranas.
The proper method for receiving this transcendental message is to hear it submissively. A challenging attitude cannot help one realize this transcendental message. One particular word is used herein for proper guidance. This word is śuśrūṣu. One must be anxious to hear this transcendental message. The desire to sincerely hear is the first qualification.
Less fortunate persons are not at all interested in hearing this Śrīmad-Bhāgavatam. The process is simple, but the application is difficult. Unfortunate people find enough time to hear idle social and political conversations, but when invited to attend a meeting of devotees to hear Śrīmad-Bhāgavatam they suddenly become reluctant. Sometimes professional readers of the Bhāgavatam immediately plunge into the confidential topics of the pastimes of the Supreme Lord, which they seemingly interpret as sex literature. Śrīmad-Bhāgavatam is meant to be heard from the beginning. Those who are fit to assimilate this work are mentioned in this sloka: “One becomes qualified to hear Śrīmad-Bhāgavatam after many pious deeds.” The intelligent person, with thoughtful discretion, can be assured by the great sage Vyasadeva that he can realize the Supreme Personality directly by hearing Śrīmad-Bhāgavatam. Without undergoing the different stages of realization set forth in the Vedas, one can be lifted immediately to the position of paramhaàsa simply by agreeing to receive this message.
