The Vishnu Purana: Book III: Chapter VII

"Yama beholding one of his servants with his noose in his hand, whispered to him, and said, 'Keep clear of the worshippers of Madhusúdana. I am the lord of all men, the Vaishńavas excepted. I was appointed by Brahmá, who is reverenced by all the immortals, to restrain mankind, and regulate the consequences of good and evil in the universe. But be who obeys Hari, as his spiritual guide, is here independent of me; for Vishńu is of power to govern and control me. As gold is one substance still, however diversified as bracelets, tiaras, or earrings, so Hari is one and the same, although modified in the forms of gods, animals, and man. As the drops of water, raised by wind from the earth, sink into the earth again when the wind subsides, so the varieties of gods, men, and animals, which have been detached by the agitation of the qualities, are reunited, when that disturbance ceases, with the eternal. He who through holy knowledge diligently adores the lotus foot of that Hari, who is reverenced by the gods, is released from all the bonds of sin; and you must avoid him as you would avoid fire fed with oil.'

"Having heard these injunctions of Yama, the messenger addressed the lord of righteousness, and said, 'Tell me, master, how am I to distinguish the worshipper of Hari, who is the protector of all beings?' Yama replied, 'You are to consider the worshipper of Vishńu, him who never deviates from the duties prescribed to his caste; who looks with equal indifference upon friend or enemy; who takes,; nothing (that is not his own), nor injures any being. Know that person of unblemished mind to be a worshipper of Vishńu. Know him to be a devout worshipper of Hari, who has placed Janárddana in his pure mind, which has been freed from fascination, and whose soul is undefiled by the soil of the Kali age. Know that excellent man to be a worshipper of Vishńu, who, looking upon gold in secret, holds that which is another's wealth but as grass, and devotes all his thoughts to the lord. Pure is he as a mountain
