Samba Purana

This text comprises a number of narratives dealing with creation, details of solar system, eclipses, geography of the earth, description of Surya and his attendants, construction of images of these deities, details of yoga, manners and customs, rites and rituals, recitations of mantras, and dāna (generosity).

[2] After the customary beginning in Chapter 1, the text consists the narrative of Krishna's son Samba being infected by leprosy after being cursed by sage Durvasa, and subsequently being cured by worshipping Surya in the temple constructed by him in Mitravana on the banks of the Chandrabhaga at what was Multan Sun Temple.

In Chapter 14, Samba engaged himself in tapas, meditating on Surya at Mitravan (identified by scholars as Multan) which came to be called Sambapur.

Chapters 26-27 of this text narrate the story of bringing the eighteen Maga Brahmins from Śākadvīpa by Samba and appointing them as the priests of the Surya temple in Mitravana.

The Gaya region is a major center of the Shakadwipiya Brahmins who use local village names as the exogamous divisions of their community.
