So there is a Bengali Vaiṣṇava poet. He says that
- śuci haya muci haya yadi kṛṣṇa tyaje
- muci haya śuci haya yadi kṛṣṇa bhaje
The purport is that if somebody takes to Kṛṣṇa consciousness, even he is born in the family of muci, then he becomes śuci. And if a person born in the brāhmaṇa family or kṣatriya family but he does not take to Kṛṣṇa consciousness, then he becomes a muci. This is also confirmed in the Bhagavad-gītā, māṁ hi pārtha vyapāśritya ye 'pi syuḥ pāpa-yonayaḥ (BG 9.32). Pāpa-yoni means muci, less than the śūdras. If he takes to Kṛṣṇa consciousness, te 'pi yānti parāṁ gatim, they are also eligible to go back to home, back to Godhead. So even a muci or a pāpa-yoni born in the low grade family, if he takes to Kṛṣṇa consciousness, he becomes a devatā. This is also confirmed in the Śrīmad-Bhāgavatam by Śukadeva Gosvāmī,
- kirāta-hūṇāndhra-pulinda-pulkaśā
- ābhīra-śumbhā yavanāḥ khasādayaḥ
- ye 'nye ca pāpā yad-apāśrayāśrayāḥ
- śudhyanti tasmai prabhaviṣṇave namaḥ
- (SB 2.4.18)
So it doesn't matter where we are born. If we take to Kṛṣṇa consciousness, then he becomes a śuddha, śuci, purified, and he is eligible to go back to home, to back to Godhead. So to take the shelter of a pure devotee means he knows what is pravṛtti and what is nivṛtti. All our Vedic literature is meant for nivṛtti. Pravṛttir eṣā bhūtānāṁ nivṛttis tu mahā-phalā. These, all living creatures, who are struggling for existence in this material world, that is their pravṛtti, to enjoy this material world. But when one becomes inclined to nivṛtti, he becomes devatā. So this Kṛṣṇa consciousness movement which was inaugurated by Śrī Kṛṣṇa Caitanya Mahāprabhu is for nivṛtti-mārga. Nivṛtti-mārga means "No more material enjoyment. Let me make progress towards Kṛṣṇa consciousness." Therefore this devotional service or bhakti-yoga, it is called nivṛtti-mārga. This is confirmed in the Śrīmad-Bhāgavatam,
- vāsudeve bhagavati
- bhakti-yogaḥ prayojitaḥ
- janayaty āśu vairāgyaṁ
- jñānaṁ ca yad ahaitukam
- (SB 1.2.7)
Bhakti-yoga... And Sarvabhauma Bhaṭṭācārya, he was a impersonalist, followers of the Śaṅkara philosophy. When he became convinced about the Vaiṣṇava philosophy, he wrote one hundred ślokas, prayers to Caitanya Mahāprabhu.
