yāṅhāra kṛpāte mlecchera haya kṛṣṇa-bhakti ke kahite pāre tāṅra vaiṣṇavatā-śakti?
“He is such a great personality that by His mercy He can convert even the meat-eaters [mlecchas] to the devotional service of Kṛṣṇa. Who, therefore, can estimate the power of His Vaiṣṇavism?
Purport
It is extremely difficult to convert a mleccha, or meat-eater, into a devotee of Lord Kṛṣṇa. Therefore anyone who can do so is situated on the highest level of Vaiṣṇavism.
— A.C. Bhaktivedanta Swami Prabhupāda
