The following are some of the standard books on sun-worship:—
(1) Aditya-hridaya—literally, the Heart of the Sun. It treats of the glory of the sun and the mode of worshipping him.
(2) Brihadāranyakopanishad and Mandula-Brahmans—portions of Yajurveda recited by Vedic Brahmans with a view to tender symbolic as well as mental prayers to the sun.
(3) Bibhrād—the fourth chapter of the Rudri.
(4) A passage in Brāhman—a portion of the Vedas, beginning with the words स्वयंभूरसि Thou art self-existent—is entirely devoted to Sun-worship.[76]
(5) Sūrya-Purāna—A treatise relating a number of stories in glorification of the sun.
(6) Sūrya-kavacha.[77]
(7) Sūrya-gīta.
(8) Sūrya-Sahasranama—a list of one thousand names of Sūrya.[78]
It is customary among Hindus to cleanse their teeth every morning with a wooden stick, known as dātan[79] and then to offer salutations to the sun in the form of a verse which means: “Oh God, the dātans are torn asunder and the sins disappear. Oh the penetrator of the innermost parts, forgive us our sins. Do good unto the benevolent and unto our neighbours.” This prayer is common in the mouths of the vulgar laity.[80]
