yad vihāyāsuraṁ bhāvaṁ
bhavān — your good self; atārṣīt — has surmounted; māyām — the illusory energy; vai — indeed; vaiṣṇavīm — of Lord Viṣṇu; jana-mohinīm — which deludes the mass of people; yat — since; vihāya — giving up; āsuram — of the demons; bhāvam — the mentality; mahā-puruṣatām — the position of an exalted devotee; gataḥ — obtained.
You have surmounted the illusory energy of Lord Viṣṇu, and because of this liberation, you have given up the demoniac mentality and have attained the position of an exalted devotee.
Lord Viṣṇu is the mahā-puruṣa. Therefore one who becomes a Vaiṣṇava attains the position of a mahā-pauruṣya. This position was attained by Mahārāja Parīkṣit. It is said in the Padma Purāṇa that the distinction between a demigod and a demon is that a demigod is a devotee of Lord Viṣṇu whereas a demon is just the opposite: viṣṇu-bhaktaḥ smṛto daiva āsuras tad-viparyayaḥ. Vṛtrāsura was considered a demon, but actually he was more than qualified as a devotee, or mahā-pauruṣya. If one somehow becomes a devotee of the Supreme Lord, whatever his position, he can be brought to the position of a perfect person. This is possible if an unalloyed devotee tries to serve the Lord by delivering him in this way. Therefore Śukadeva Gosvāmī says in Śrīmad-Bhāgavatam (2.4.18):
ābhīra-śumbhā yavanāḥ khasādayaḥ
ye ’nye ca pāpā yad-apāśrayāśrayāḥ
śudhyanti tasmai prabhaviṣṇave namaḥ
“Kirātas, Hūṇas, Āndhras, Pulindas, Pulkaśas, Ābhīras, Śumbhas, Yavanas and members of the Khasa races, and even others addicted to sinful acts can be purified by taking shelter of the devotees of the Lord, for He is the supreme power. I beg to offer my respectful obeisances unto Him.” Anyone can be purified if he takes shelter of a pure devotee and molds his character according to the pure devotee’s direction. Then, even if one is a Kirāta, Āndhra, Pulinda or whatever, he can be purified and elevated to the position of a mahā-pauruṣya.
