Bhavān hi veda tat sarvaṁ yan māṁ dharmānupṛcchasi (SB 1.16.25). So, Dharmarāja, or Yamarāja, he is one of the twelve authorized persons for maintaining properly the human civilization. The principle is dharma. Dharma means not a religious sentiment. Dharma means occupational duty. Everyone has got some occupational duty. So dharmaṁ tu sākṣād bhagavat-praṇītam (SB 6.3.19). That occupational duty is assigned by the Supreme Personality of Godhead. Tena tyaktena bhuñjīthāḥ (ISO 1). Actually, the dharma principle, as we learn from Bhagavad-gītā... Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). Don't create, manufacture, your principle of religion, concocted. That is the difficulty. Dharmaṁ tu sākṣād bhagavat-praṇītam (SB 6.3.19). We have several times explained this, that dharma means-dharma, as it is translated in English, "religion"—religion means to obey the laws of God. That is religion, not a sentimental system of religious system we manufacture. That kind of dharma will not help us. Therefore, in the Śrīmad-Bhāgavatam, in the beginning it is said, dharmaḥ projjhita-kaitavo 'tra: (SB 1.1.2) "Cheating type of religious system is kicked out." That is Bhāgavata-dharma. No cheating. In the name of cheating and dharma, religious principle, that will not help the human civilization.
The real dharma... The real dharma is stated by God Himself. Dharmaṁ tu sākṣād bhagavat-praṇītam (SB 6.3.19). You haven't got to learn from anywhere else but from God Himself. So that is explained very nicely in the Bhagavad-gītā, sarva-dharmān parityajya mām... (BG 18.66). To surrender to the Supreme Personality of Godhead, that is religion. Not only surrender, but to act as He desires, or you become a lover of God. This is first-class religion. We have several times explained. Sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje (SB 1.2.6). That type of religion is first-class which teaches you how to become a lover of God. If you become lover, then your life is successful. Then you'll do everything for God. Otherwise, you'll simply question, "Why shall I do that? Why shall I do that? Why shall I...?" That means there is no love. That is training. Just like a novice is being trained up, and he has no love, so he'll question that "Why shall I do it? Why shall I do it? Why shall I do? What benefit I shall get?" So many questions will be there. But when there is love, there is no question. So therefore in the Bhagavad-gītā, after teaching so many things, yoga, jñāna, karma and so many other things, at last, Kṛṣṇa says, sarva-guhyatamam: "Now I am speaking to you the most confidential instruction." What is that? Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja... (BG 18.66). This is the most confidential.
