Garudapurana 1.33

The glorious Garuḍa Mahāpurāṇa, Chapter 33. / Rudra said: / Speak to me of the worship of Sudarśana, O wielder of the conch and mace, / by performing which planetary afflictions, diseases, and all else are surely destroyed.

Hari said: / Hear, O you whose banner bears a bull, the worship of the discus Sudarśana: / one should first take a bath, and then worship Hari.

The placement is performed with the root-mantra; hear the root-mantra: / preceded by the praṇava, the mantra is ‘Sahasrāra huṃ phaṭ namaḥ’.

It is proclaimed as the destroyer of all wicked ones, the breaker of mantras; / one should meditate upon the god Sudarśana in the pure, auspicious lotus of the heart,

Bearing conch, discus, mace, and lotus, gentle, wearing a crown; / having invoked the god in the maṇḍala by the previously stated procedure, O Hara,

One should worship him, O Maheśvara, with articles of worship beginning with perfume and flowers; / having worshipped, a man should recite the mantra one hundred and eight times.

Whoever performs this excellent worship of the discus in this way, O Rudra, / freed from all diseases, shall attain the world of Viṣṇu.

Afterwards one should recite this hymn, which destroys all illnesses: / ‘Obeisance to Sudarśana, who has the brilliance of a thousand suns;

To the one blazing with a garland of flames, the thousand-spoked one, the eye, / to the destroyer of all wicked beings, the crusher of all sins;

To the auspicious discus, the great discus, the breaker of all mantras, / to the progenitor, the upholder of the world, obeisance to the destroyer of the world;

To the protector of the worlds, the destroyer of wicked asuras, / to the fierce, and gentle, and obeisance, obeisance to the wrathful one;

Obeisance to the one whose form is the eye, the shatterer of the fear of worldly existence, / the breaker of the cage of delusion, and obeisance, obeisance to the auspicious one;

To the one whose form is planets and super-planets, obeisance to the lord of the planets; / to Time, to Death, and obeisance, obeisance to the terrible one;

To the giver of grace to devotees, and obeisance, obeisance to the protector of devotees; / to the one whose form is Viṣṇu, the tranquil one, and the bearer of weapons;

To the weapon of Viṣṇu, to the discus, obeisance, again and again obeisance!’ / Thus the greatly meritorious hymn of the discus has been proclaimed to you.

He who recites it with supreme devotion goes to the world of Viṣṇu; / and the restrained person who recites the rite of worshipping the discus, O Rudra, / having reduced sin to ashes, becomes fit for the world of Viṣṇu.

Thus in the glorious Garuḍa Mahāpurāṇa, in the first section called the first part, in the section on conduct, the thirty-third chapter entitled ‘The Rule for the Worship of Sudarśana’.
