भक्त्याहमेकया ग्राह्य: श्रद्धयात्मा प्रिय: सताम् ।
भक्ति: पुनाति मन्निष्ठा श्वपाकानपि सम्भवात् ॥ २१ ॥
bhaktyāham ekayā grāhyaḥ

bhaktiḥ punāti man-niṣṭhā
śva-pākān api sambhavāt
Only by practicing unalloyed devotional service with full faith in Me can one obtain Me, the Supreme Personality of Godhead. I am naturally dear to My devotees, who take Me as the only goal of their loving service. By engaging in such pure devotional service, even the dog-eaters can purify themselves from the contamination of their low birth.
