“ ‘Kirātas, Hūnas, Āndhras, Pulindas, Pukkaśas, Ābhīras, Śumbhas, Yavanas and members of the Khaśa races, and even others who are addicted to sinful acts, can be purified by taking shelter of the devotees of the Lord, due to His being the supreme power. I beg to offer my respectful obeisances unto Him.’
This is a quotation from Śrīmad-Bhāgavatam (2.4.18). This verse was spoken by Śukadeva Gosvāmī when Parīkṣit Mahārāja asked him for a description of the creation. While offering obeisances to the Supreme Personality of Godhead, Śukadeva Gosvāmī described the unlimited potencies of Lord Viṣṇu, who can purify the lowborn creatures mentioned herein.
