Real dharma, constitutional position of the living entity, is to serve Kṛṣṇa. That is real dharma. Kṛṣṇa also confirms in the Bhagavad-gītā, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). So mām ekaṁ śaraṇaṁ vraja, simply unto Kṛṣṇa, surrender, that is real dharma. Otherwise it is pseudo-religious principle, pretentious, dharmaḥ projjhita-kaitavaḥ.
There are two kinds of dharma: kaitava, cheating religious system, and real religious system. That is the subject matter of Śrīmad-Bhāgavatam: to teach people the real religious system. In this chapter also, Sūta Gosvāmī has explained, sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje (SB 1.2.6). You can execute your occupational duties or religious system very nicely, but if you do not develop your love for God, Kṛṣṇa, then it is simply useless labor. It has no meaning. The test is how much you have developed your dormant consciousness for loving Kṛṣṇa. That is the test.
Bhaktiḥ pareśānubhavo viraktir anyatra syāt (SB 11.2.42). If actually one is making progress in devotional service, he must be detestful to any other system. They are not interested. Actual interest is Kṛṣṇa, Viṣṇu. That is our actual interest. Especially when one comes to the form of a human being, his special interest should be how to approach Viṣṇu. Na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). Svārtha-gatim, self-interest.
Everyone is inclined for his self-interest, but they do not know what is real self-interest. Somebody is thinking, "To satisfy the senses, body, that is self-interest." Somebody is thinking, "To satisfy the mind, whims of the mind, that is self-interest." Somebody is thinking, "Liberation of the self, mokṣa, mokṣa-vāñchā." That is also not self-interest. But when one thinks in terms of serving the Supreme Personality of Godhead, that is real self-interest.
So na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). People do not know.
(break) . . . svārtha-gatiṁ hi viṣṇum. Real self-interest is to become Vaiṣṇava, servitor of Viṣṇu. Viṣṇur asya devatā iti vaiṣṇava. That is real self-interest. Why people do not become Vaiṣṇava? Generally they worship various demigods—devotee of Lord Śiva, devotee of Goddess Kali, Durgā, so many. But they have been condemned by Bhagavad-gītā, spoken by Kṛṣṇa Himself: kāmais tais tair hṛta-jñānā yajante anya-devatāḥ. Hṛta-jñānāḥ (BG 7.20).
Śrīla Viśvanātha Cakravartī Ṭhākura gives his comment, hṛta-jñānāḥ naṣṭa-buddhayaḥ: "One who has lost his intelligence, they are inclined to worship other demigods." Kāmais tais tair hṛta-jñānāḥ. Because they do not know what is his self-interest. He thinks that his self-interest is to give comfort to this body, the senses, sense-gratification. That is his misguided self-interest. Durāśayā ye bahir-artha-māninaḥ (SB 7.5.31). Bahir-artha-māninaḥ. Bahir-artha means external energy. This body, gross body and the subtle body, they are made of the external energy. Bhūmir āpo 'nalo vāyuḥ khaṁ mano buddhir eva ca (BG 7.4).
