Vishnupurana 3.8.5

3.8.5

phalaṃ cārādhite viṣṇau yat puṃsām abhijāyate
sa cāha pṛṣṭo yat tena tan maitreyākhilaṃ śṛṇu //

Sagara having bowed down before Aurva, the descendant of Bhrigu, asked him what were the best means of pleasing Vishńu, and what would be the consequence of obtaining his favour. Aurva replied, "He who pleases Vishńu obtains all terrestrial enjoyments; heaven and a place in heaven; and what is best of all, final liberation: whatever he wishes, and to whatever extent, whether much or little, he receives it, when Achyuta is content with him. In what manner his favour is to be secured, that also I will, oh king, impart to you, agreeably to your desire. The supreme Vishńu is propitiated by a man who observes the institutions of caste, order, and purificatory practices: no other path is the way to please him. He who offers sacrifices, sacrifices to him; he who murmurs prayer, prays to him; he who injures living creatures, injures him; for Hari is all beings. Janárddana therefore is propitiated by him who is attentive to established observances, and follows the duties prescribed for his caste. The Brahman, the Kshatriya, the Vaiśya, and the Śúdra, who attends to the rules enjoined his caste, best worships Vishńu. Keśava is most pleased with him who does good to others; who never utters abuse, calumny, or untruth; who never covets another's wife or another's wealth, and who bears ill-will towards none; who neither beats nor slays any animate or inanimate thing; who is ever diligent in the service of the gods, of the. Brahmans, and of his spiritual preceptor; who is always desirous of the welfare of all creatures, of his children, and of his own soul; in whose pure heart no pleasure is derived from the imperfections of love and hatred. The man, oh monarch, who conforms to the duties enjoined by scriptural authority for every caste and condition of life, is he who best worships Vishńu: there is no other mode."
