What is our dharma? What is our compulsory duty? I have several times analyzed this fact. Our compulsory duty is to serve. Compulsory duty. Every one of us is serving, and all the boys and girls present here can know it. And nobody can deny that he or she is not serving. Everyone is serving. That is our compulsory duty.
I may change my faith. I am Christian or I am Hindu, I may change myself to become a Muhammadan or Christian or Hindu. But my real occupational duty to render service to others, that cannot be changed. That is the real enunciation of religion. And therefore in the Vedic system it is called sanātana-dharma. Sanātana-dharma means that eternal occupational duty which you cannot cease.
Now, Prahlāda Mahārāja is advising that dharmān bhāgavatān. Bhāgavatān means . . . Bhāgavata means pertaining to Bhagavān. And Bhagavān means to the Supreme Personality of Godhead. So bhāgavata is the adjective form of the noun word Bhagavān. Bhaga, real form of the word is bhagavat. Bhagavat. Vat means possessing, and bhaga means opulences.
One who possess all the opulences, He's called bhagavat. And from bhagavat this word has come, bhāgavata. So bhāgavata means pertaining to God and His devotees. That is called bhāgavata. Just like this book is called Bhāgavata because it deals only with the subject matter of the Supreme Personality of Godhead, nothing more. Bās. Therefore it is called Bhāgavata. And you'll find description in this book, the dealings between Bhagavān, the Supreme Personality of Godhead, and His devotees.
