“I am the very light of the sun and the moon.[61]” Being the embodiment or the fountain of light, the sun imparts his lustre either to the bodies or to the eyes of his devotees. It is said that a Rajput woman of Gomātā in Gondal and a Brahman of Rajkot were cured of white leprosy by vows in honour of the sun.[62] Similar vows are made to this day for the cure of the same disease. Persons in Kathiawar suffering from ophthalmic disorders, venereal affections, leucoderma and white leprosy are known to observe vows in honour of the sun.[63]

The Parmār Rajputs believe in the efficacy of vows in honour of the sun deity of Māndavrāj, in curing hydrophobia.[64]

Women believe that a vow or a vrat made to the sun is the sure means of attaining their desires. Chiefly their vows are made with the object of securing a son. On the fulfilment of this desire, in gratitude to the Great Luminary, the child is often called after him, and given such a name as Suraj-Rām, Bhānu-Shankar, Ravi-Shankar, Adit-Rām.[65]

Many cradles are received as presents at the temple of Māndavrāj, indicating that the barren women who had made vows to the deity have been satisfied in their desire for a son, the vows being fulfilled by the present of such toy-cradles to the sun. In the case of rich donors, these cradles are made of precious metal.[66]

At Mandvara, in the Muli District of Kathiawar, the Parmār Rajputs, as well as the Kāthis, bow to the image of the sun, on their marriage-day, in company with their newly-married brides.[66] After the birth of a son to a Rajputani, the hair on the boy’s head is shaved for the first time in the presence of the Māndavrāj deity,[67] and a suit of rich clothes is presented to the image by the maternal uncle of the child.[68]

The sun is सर्वसाक्षी the observer of all things and nothing can escape his notice.[69] His eye is believed to possess the lustre of the three Vedic lores, viz., Rigveda, Yajurveda and Sāmaveda, and is therefore known by the name of वेदत्रयी. The attestation of a document in his name as Sūrya-Nārāyana-Sākshi is believed to be ample security for the sincerity and good faith of the parties.[70] Oaths in the name of the sun are considered so binding that persons swearing in his name are held to be pledged to the strictest truth.[71]

Virgin girls observe a vrat, or vow, called the ‘tili-vrat’ in the sun’s honour, for attaining अखंड सौभाग्य—eternal exemption from widowhood. In making this vrat, or vow, the votary, having bathed and worshipped the sun, sprinkles wet red-lac drops before him.[72]

According to Forbes’s Rāsmālā, the sun revealed to the Kāthis the plan of regaining their lost kingdom, and thus commanded their devout worship and reverence. The temple named Suraj-deval, near Thān, was set up by the Kāthis in recognition of this favour. In it both the visible resplendent disc of the sun and his image are adored.[73]

People whose horoscopes declare them to have been born under the Sūrya-dashā, or solar influence, have from time to time to observe vows prescribed by Hindu astrology.[74]

Cultivators are said to observe vows in honour of the sun for the safety of their cattle.[75]
