The evidence,²⁴ however, for the latter assumption is quite insufficient.²⁵ The theory of the Aitareya Brāhmaṇa²⁶ is that the sun merely reverses its bright side at night, turning its light on the stars and the moon while it retraverses its course to the east; and it has been shown²⁵ that this is probably the doctrine of the Rigveda also.²⁷ See also Sūrya and Candramās. For the Vedic knowledge of the planets, see Graha. - [Previous: v1.c3.s18.380](https://indike.org/pramana/ins.reference.macdonell-keith-1912.v1.c3.s18.380) - [Next: v1.c3.s18.382](https://indike.org/pramana/ins.reference.macdonell-keith-1912.v1.c3.s18.382) - [Up: v1.c3.s18](https://indike.org/pramana/ins.reference.macdonell-keith-1912.v1.c3.s18) ## Linked texts (2) - [Aitareyabrāhmaṇa](https://indike.org/pramana/in.veda.brahmana.aitreya) — Mahidāsa Aitareya, Sanskrit - [Ṛgvedasaṃhitā](https://indike.org/pramana/in.veda.samhita.rg) — Sanskrit --- Source: [https://indike.org/pramana/ins.reference.macdonell-keith-1912.v1.c3.s18.381](https://indike.org/pramana/ins.reference.macdonell-keith-1912.v1.c3.s18.381) · Pramāṇa
