In the sacred Garuda Purana, within the Purva Khanda and the Achara Kanda, the thirtieth chapter concludes with the teachings on the method of worship of Shridhara, the form of Vishnu. As the narrative continues, a devotee, eager to deepen his understanding, respectfully asks, "O Lord of the universe, please tell me again about the worship, O Master." The answer comes from the Bull-bannered One, who declares, "I shall now explain the worship of the god Vishnu." The process begins with the devotee bathing and performing the twilight ritual, preparing himself to enter the sacrificial chamber. There, he places the entire root mantra, allowing it to pervade both hands. The mantra is: "Om, śrīṃ, hrīṃ, obeisance to Shridhara Vishnu," who is praised as the remover of all diseases and the destroyer of planetary afflictions. A practitioner skilled in mantras then assigns mantras to the limbs: "Om hīṃ" to the head with "svāhā," "Om haiṃ" to the armor with "huṃ," and "Om haḥ" to the missile with "phaṭ." This mantra is thus declared to mighty Vishnu. Next, the devotee meditates on Supreme Vishnu, envisioning Him abiding within the cavity of the heart. Vishnu is adorned with the Śrīvatsa mark, the Kaustubha gem, and garlanded with a wreath of forest flowers. Meditating with the thought "I am Vishnu," and having performed purification and related acts, the devotee produces the ritual egg and breaks it with the syllable "Om." Afterward, self-worship is performed with auspicious incense, flowers, and other offerings. With these mantras, the devotee is instructed to listen, as Mahadeva and Shankara are addressed: "Om, obeisance to Acyuta, along with all his retinue; Om, obeisance to the Creator; Om, obeisance to Yamuna; Om, obeisance to the Lord of the Lotus; Om, obeisance to the Fierce One; Om, obeisance to the Supporting Power; Om, obeisance to the Infinite; Om, obeisance to Dharma; Om, obeisance to Dispassion; Om, obeisance to Adharma; Om, obeisance to Non-dispassion; Om, obeisance to Sattva; Om, obeisance to Tamas; Om, obeisance to Nala; Om, obeisance to the Solar Orb; Om, obeisance to the Fire Circle; Om, obeisance to the Uplifting One; Om, obeisance to Action; Om, obeisance to Humility; Om, obeisance to Īśānī." These mantras are used in worship with sandalwood, flowers, and similar offerings. Having invoked the Lord in the maṇḍala, Rudra is told to worship the Supreme Lord. The assignment of mantras (nyāsa) performed on oneself is also to be done for the deity from the beginning. The devotee then bathes the deity, offers clothing, and gives water for sipping. After this, the devotee recites the mantra while circumambulating and offers it there, always using the root-mantra of the deity. The mantras for this ritual include: "Om hām, obeisance to the heart; Om hūm, obeisance to the crest; Om haum, obeisance to the three eyes; Om, obeisance to Śrī; Om, obeisance to Padmā; Om, obeisance to Gadā; Om, obeisance to Kaustubha; Om, obeisance to the wearer of yellow garments; Om, obeisance to Musala; Om, obeisance to Aṅkuśa; Om, obeisance to Śara; Om, obeisance to Nārāda; Om, obeisance to the Bhāgavatas; Om, obeisance to the supreme teachers; Om, obeisance to Agni, lord of brilliance, with his vehicle and retinue; Om, obeisance to Nirṛti, lord of the Rākṣasas, with his vehicle and retinue; Om, obeisance to Vāyu, lord of life, with his vehicle and retinue; Om, obeisance to Īśāna, lord of knowledge, with his vehicle and retinue; Om, obeisance to Brahmā, lord of the worlds, with his vehicle and retinue; Om, obeisance to Śakti, huṃ phaṭ; Om, obeisance to Khaḍga, huṃ phaṭ; Om, obeisance to Dhvaja, huṃ phaṭ; Om, obeisance to Triśūla, huṃ phaṭ; Om, obeisance to Padma, huṃ phaṭ." With these mantras, Mahādeva is told that the limbs and other aspects are to be worshipped by men. With the accompanying hymn, the devotee praises the imperishable Supreme Self: "Obeisance to Vishnu, to Vāsudeva, and to the sustainer of existence. Obeisance to the lord of the gods and to the lord of sacrifices. Obeisance to the victorious one among all the gods, to the all-pervading great soul. Obeisance to the overseer of the worlds, who acts for the welfare of all beings. Repeated obeisance to the bestower of boons, to the peaceful one, to the most excellent." Having offered praise, the devotee meditates in his heart on the imperishable form of Brahman. Alternatively, whoever recites the root-mantra attains Hari. This teaching is declared to be the supreme, most secret mystery, bestowing both enjoyment and liberation; whoever hears it or has it recited will attain the world of Vishnu. The narrative then shifts as the devotee asks, "Tell me about the worship of the five principles, O bearer of conch, discus, and mace!" The reply comes: "O Shankara, steadfast in vows, I will explain to you the worship of the five principles. Listen, O Mahādeva, for it is pure and destroys the effects of the Kali age." Vāsudeva is described as eternal, pure, all-pervading, and stainless. Vishnu, who grants grace to the worlds, is the destroyer of all evil. He also abides in the form of Pradyumna, known as Aniruddha. The mantras designating these forms are revealed: "Om, āṃ, salutations to Saṃkarṣaṇa; Om, salutations to Aniruddha." Thus, the sacred instructions for worship and the invocation of Vishnu and his forms are lovingly imparted, guiding the devotee on the path to spiritual fulfillment and liberation.
