*Arghya*⁷⁵⁶ (offering water out of respect to the sun) consists in taking water in one's joined hands, repeating the Gāyatrī verse over it and standing facing the sun and casting it up thrice. If a man cannot have water (being at the time of Saṁdhyā on a road or in jail &c.) he could use dust for water. The Tai. Ār. II. 2 says that a brāhmaṇa contemplating the rising and setting sun and doing obeisance to it by going from left to right attains all bliss, since this Āditya is *Brahma*.
