bhaktyā—by devotional service; aham—I, the Supreme Personality of Godhead; ekayā—unflinching; grāhyaḥ—obtainable; śraddhayā—by faith; ātmā—the most dear; priyaḥ—to be served; satām—by the devotees; bhaktiḥ—the devotional service; punāti—purifies; mat-niṣṭhā—fixed only on Me; śva-pākān—the lowest grade of human beings, who are accustomed to eating dogs; api—certainly; sambhavāt—from all faults due to birth and so on.
" 'Being very dear to the devotees and sādhus, I am attained through unflinching faith and devotional service. This bhakti-yoga system, which gradually increases attachment for Me, purifies even a human being born among dog-eaters. That is to say, everyone can be elevated to the spiritual platform by the process of bhakti-yoga.'
This verse is from Śrīmad-Bhāgavatam (11.14.21).
