SB 8.16.28
nirvartitatma-niyamo
devam arcet samahitah
arcayam sthandile surye
jale vahnau gurav api
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thereafter, one should perform his daily spiritual duties and then, with great attention, offer worship to the Deity of the Supreme Personality of Godhead, and also to the altar, the sun, water, fire and the spiritual master.
