Garudapurana 1.17

The glorious and great Garuḍapurāṇa — 17
Hari said:
Again I shall explain the worship of the Sun as it was told to the Giver of Wealth [Kubera]:
one should draw an eight-petalled lotus with a pericarp in a pure place.

Then, having formed the invocation mudrā, one should invoke the Sun.
Having established Khakholka, one should form the mudrā consisting of the mantra.

One should place the heart of the deity in the southeast direction, O Śiva;
in the northeast one should place the head, and in the southwest one should deposit the topknot;

with concentrated mind one should place dharma in the east;
and in the northwest the eye, and in the west the weapon.

In the northeast one should place Soma, and in the east Mars;
in the southeast the son of Soma [Mercury], and in the south Bṛhaspati;

in the southwest the preceptor of the Dānavas [Venus], in the west Saturn;
in the northwest Ketu, and in the north Rāhu.

In the second circuit one should worship the twelve Suns:
Bhaga, Sūrya, and Aryaman, Mitra, and Varuṇa,

Savitṛ, Dhātṛ, and Vivasvat of great might,
Tvaṣṭṛ, Pūṣan, Indra, and the twelfth is declared to be Viṣṇu.

Beginning from the east, a person should worship with faith the gods Indra and the others,
as well as Jayā, Vijayā, Jayantī, and Aparājitā;
and one should worship the serpents Śeṣa, Vāsuki, and so forth.

Thus ends the seventeenth chapter, named 'Rules for the Worship of the Sun,' in the ritual conduct section, designated the first part of the first section in the glorious and great Garuḍapurāṇa.
