Garudapurana 1.58

Garuḍa Purāṇa 58
Hari said: / I will explain the dimensions and structure of the sun and the rest; hear from me. / The chariot of the Sun measures nine thousand yojanas;

likewise, O bull-bannered [Śiva], its pole is twice that. / Its axle measures fifteen million,

plus seven hundred thousand yojanas, and upon it the wheel is fixed. / It has three naves, five spokes, and six rims, imperishable in nature;

consisting of the year, the entire wheel of Time is mounted upon it. / The second axle of the Sun is forty thousand [yojanas],

and five and a half more, O bull-bannered one, for the chariot. / The measure of the two axles is the measure of the two half-yokes.

The short axle rests on Dhruva by its half-yoke for the chariot, / while the wheel on the second axle rests upon Mount Mānasa.

Gāyatrī, together with Bṛhatī, Uṣṇih, Jagatī, and Triṣṭubh, / Anuṣṭubh and Paṅkti—these metres are declared to be the horses of the Sun.

Dhātṛ, Kratusthalā, Pulastya, Vāsuki, / the chariot-maker Rathakṛt, the leader Heti, and Tumburu reside [with the Sun] in the month of Caitra.

Aryaman, Pulaha, Rathaujas, Puñjikasthalā, / Praheti, Kacchanīra, and Nārada reside [with him] in Mādhava.

Mitra, Atri, Takṣaka, the rākṣasa Pauruṣeya, Menakā, / Hāhā, and Rathasvana abide on the Sun's chariot in Jyeṣṭha.

Varuṇa, Vasiṣṭha, Rambhā, Sahajanyā, Kuhū, Budha, / Rathacitra, and Śukra dwell [on it] in the month named Āṣāḍha.

Indra, Viśvāvasu, Śrotra, Elāpatra, Aṅgiras, / and Pramlocā—these [and other] serpents are indeed on the Sun in Śrāvaṇa.

Vivasvat, Ugrasena, Bhṛgu, Āpūraṇa, / Anumlocā, Śaṅkhapāla, and Vyāghra are stationed in Bhādrapada.

Pūṣan, Suruci, Dhātṛ, Gautama, Dhanañjaya, / Suṣeṇa, and the other, Dhṛtācī, dwell with the Sun in Āśvayuja.

Viśvāvasu, Bharadvāja, Parjanya, Airāvata, / Viśvācī, Senajit, and Āpa are the presiding deities in Kārtika.

Aṃśu, Kaśyapa, Tārkṣya, Mahāpadma, Urvaśī, / Citrasena, and Vidyut are the presiding deities in Mārgaśīrṣa.

Kratu, Bharga, Ūrṇāyu, Sphūrja, Karkoṭaka, / Ariṣṭanemi, and another apsaras, Pūrvacitti— / these seven dwell in the solar disc during the month of Pauṣa.

Tvaṣṭṛ, Jamadagni, Kambala, Tilottamā, / Brahmāpeta, Ṛtajit, and Dhṛtarāṣṭra as the seventh— / these seven dwell in the solar disc during the month of Māgha.

Viṣṇu, Aśvatara, Rambhā, Sūryavarcas, Satyajit, / Viśvāmitra, and the rākṣasa Yajñāpeta dwell [there] in Phālguna.

Magnified by the power of Viṣṇu in the disc of the Sun, O Brahman, / the sages praise the Sun, and gandharvas sing before him.

Apsarases dance along; night-wanderers follow the Sun; / serpents draw [his chariot], and yakṣas take hold of the reins.

Likewise, the Bālakhilyas surround and sit around him. / The chariot of the Moon has three wheels, and its horses have the lustre of kunda flowers.

Yoked to the left and right are ten [horses], by which he traverses. / The chariot of the son of the Moon (Budha) is produced from water, fire, and sky;

it is yoked with eight yellowish horses swift as the wind. / Furnished with a fender and an axle, yoked with horses born of the earth,

bearing quivers and banners, is the great chariot of Śukra. / The chariot of the son of the Earth (Mars) resembles molten gold;

drawn by eight horses, golden, and glorious is the great chariot of Bhauma (Mars);

it is yoked with ruby-red horses born of fire. / In a golden chariot yoked with eight pale horses,

Bṛhaspati, remaining [there], stays for a year in each zodiac sign. / Having mounted a chariot yoked with dapple-grey horses born of space,

Śanaiścara (Saturn), moving slowly, proceeds gradually. / The eight horses of Svarbhānu (Rāhu), resembling black bees, [draw] a dusky chariot;

yoked once, O lord of beings, they carry it unceasingly, O Śiva. / Likewise, the horses of the chariot of Ketu are eight, swift as the wind.

they have the smoky color of straw and are reddish like lac-dye. / The continents, rivers, mountains, and oceans of the worlds are the body of Hari.
