Just like law. Law means it is given by the government. You cannot manufacture law. Law means government law. Not that privately you have manufactured some law, that will be accepted as law. No, that is not law. Similarly, dharma means which is given by God. That is dharma or religious system. Dharmaṁ tu sākṣād bhagavat-praṇītam (SB 6.3.19). In the Vedic injunction you'll find, dharma means the law which is given by God. So you must know what is God and what order He is giving. That is dharma. Otherwise, it is not dharma. Therefore in the Śrīmad-Bhāgavatam it is said, dharmaḥ projjhita-kaitavo 'tra (SB 1.1.2): "In this Śrīmad-Bhāgavatam, kaitava-dharma . . ." Kaitava means cheating, " . . . a cheating type of religious system, is completely kicked out in this Śrīmad-Bhāgavatam." Dharmaḥ projjhita-kaitavo 'tra paramo nirmatsarāṇāṁ satām (SB 1.1.2). It is for the best person. Unless one is the best person, he cannot take up this dharma, bhāgavata-dharma. This very word is there, for whom the bhāgavata-dharma is meant for. So in the beginning, so that others may not be misled that "Dharma means whatever I accept, that is dharma . . ." They are preaching now in India, yata mat tata path: "Whatever you accept, that is dharma." No. Dharma means bhāgavata-dharma. Whatever Bhagavān says, or God says, that is dharma.
And God is one. There cannot be different Gods. If God has got competitors, then He is not God. There cannot be Hindu God, Muslim God, Christian God, or other conception of God. God is one. God cannot be Hindu, Muslim, Christian. So . . . And His order is also one. That is the instruction in the Bhagavad-gītā. Kṛṣṇa says, God says, that sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). Real dharma is to surrender unto God.
