If one can understand Bhagavad-gītā perfectly, and he takes to this system of religion, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja, then he can understand Śrīmad-Bhāgavatam. Because where Bhagavad-gītā is ended, Śrīmad-Bhāgavatam begins from that point. Because in the Śrīmad-Bhāgavatam, in the introductory verses, Vyāsadeva says, dharmaḥ projjhita-kaitavo 'tra paramo nirmatsarāṇām (SB 1.1.2): "This, this Śrīmad-Bhāgavatam is not ordinary type of religious system, because from this Bhāgavatam, kaitava, cheating type of religion, is completely swept away, kicked out, thrown away." Dharmaḥ projjhita-kaitavo 'tra. And upon this, the great commentator Śrīdhara Svāmī, he says, atra mokṣa-vāñchā api nirasta. Because we know dharma-artha-kāma-mokṣa (SB 4.8.41, CC Adi 1.90). So Śrīdhara Svāmī says that dharmaḥ projjhita . . . because people are becoming religious for mokṣa, liberation. So Śrīdhara Svāmī says that up to the end of mokṣa-vāñchā, desire for liberation, that is also rejected. The . . . because mokṣa is also not our ultimate goal of life. Mokṣa means to get relief from the material bondage. But if you do not get engagement of spiritual life, then mokṣa is also cheating because you'll fall down again.
I have repeatedly said that cure of disease is all right, but after curing, if you are not engaged in your healthy activities, then means . . . that means that your disease is again, will be relapsed. The śāstra says therefore, āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adhaḥ (SB 10.2.32). One sometimes, after practicing much severe austerities and penances, he can approach the Brahman, paraṁ padam, that is Brahman realization, or Brahmaloka. Patanty adhaḥ. But from there also you will fall down.
