"when one is elevated to the platform on which he can worship the Deity, his previous birth does not matter"

SB Canto 4

In our Kṛṣṇa consciousness society, unless one is twice initiated—first by chanting Hare Kṛṣṇa and second by the Gāyatrī mantra—he is not allowed to enter the kitchen or Deity room to execute duties. However, when one is elevated to the platform on which he can worship the Deity, his previous birth does not matter.

SB 4.31.10, Purport:

It is also stated that in this age of Kali, everyone is śūdra due to the absence of the garbhādhāna-saṁskāra. This is the Vedic system. According to the pāñcarātrika system, however, even though everyone is a śūdra due to the absence of the garbhādhāna-saṁskāra, if a person has but a little tendency to become Kṛṣṇa conscious, he should be given the chance to elevate himself to the transcendental platform of devotional service. Our Kṛṣṇa consciousness movement adopts this pāñcarātrika-vidhi, as advised by Śrīla Sanātana Gosvāmī, who says:

yathā kāñcanatāṁ yāti

kāṁsyaṁ rasa-vidhānataḥ

tathā dīkṣā-vidhānena

dvijatvaṁ jāyate nṛṇām

"As bell metal, when mixed with mercury, is transformed to gold, a person, even though not golden pure, can be transformed into a brāhmaṇa, or dvija, simply by the initiation process." (Hari-bhakti-vilāsa 2.12) Thus if one is initiated by a proper person, he can be accepted as twice-born immediately. In our Kṛṣṇa consciousness movement, we therefore offer the student his first initiation and allow him to chant the Hare Kṛṣṇa mahā-mantra. By chanting the Hare Kṛṣṇa mahā-mantra regularly and following the regulative principles, one becomes qualified to be initiated as a brāhmaṇa, because unless one is a qualified brāhmaṇa he cannot be allowed to worship Lord Viṣṇu. This is called yājñika janma. In our Kṛṣṇa consciousness society, unless one is twice initiated—first by chanting Hare Kṛṣṇa and second by the Gāyatrī mantra—he is not allowed to enter the kitchen or Deity room to execute duties. However, when one is elevated to the platform on which he can worship the Deity, his previous birth does not matter.

caṇḍālo 'pi dvija-śreṣṭho

hari-bhakti-parāyaṇaḥ

hari-bhakti-vihīnaś ca

dvijo 'pi śvapacādhamaḥ

"Even if one is born in the family of a caṇḍāla, if one engages in the devotional service of the Lord, he becomes the best of brāhmaṇas. But even a brāhmaṇa who is devoid of devotional service is on the level of the lowest dog-eater." If a person is advanced in devotional service, it does not matter whether he was born in a caṇḍāla family. He becomes purified.
