As stated in the previous verse, dharmam bhagavatam, real religious principles, are bhagavata-dharma, the principles described in Srimad-Bhagavatam itself or in Bhagavad-gita, the preliminary study of the Bhagavatam. What are these principles? The Bhagavatam says, dharmah projjhita-kaitavo tra: [SB 1.1.2] in Srimad-Bhagavatam there are no cheating religious systems.

Such a religious system begins with tan-nama-grahana, chanting of the holy name of the Lord (sravanam kirtanam visnoh smaranam pada-sevanam [SB 7.5.23]). After chanting the holy name of the Lord and dancing in ecstasy, one gradually sees the form of the Lord, the pastimes of the Lord and the transcendental qualities of the Lord. This way one fully understands the situation of the Personality of Godhead. One can come to this understanding of the Lord, how He descends into the material world, how He takes His births and what activities He performs, but one can know this only by executing devotional service. As stated in Bhagavad-gita, bhaktya mam abhijanati: [Bg. 18.55] simply by devotional service one can understand everything about the Supreme Lord. If one fortunately understands the Supreme Lord in this way, the result is tyaktva deham punar janma naiti: [Bg. 4.9] after giving up his material body, he no longer has to take birth in this material world. Instead, he returns home, back to Godhead. That is the ultimate perfection. Therefore Krsna says in Bhagavad-gita (8.15):
