Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 17

Sanskrit:

मण्डलं देवयजनं दीक्षा संस्कार आत्मन: ।परिचर्या भगवत आत्मनो दुरितक्षय: ॥ १७ ॥

ITRANS:

maṇḍalaṁ deva-yajanaṁdīkṣā saṁskāra ātmanaḥparicaryā bhagavataātmano durita-kṣayaḥ

Translation:

The sun globe is the place where the Supreme Lord is worshiped, spiritual initiation is the means of purification for the spirit soul, and rendering devotional service to the Personality of Godhead is the process for eradicating all one’s sinful reactions.

Purport:

One should meditate on the fiery sun globe as a place where God is worshiped. Lord Kṛṣṇa is the reservoir of all effulgence, and thus it is fitting that He be properly worshiped on the glowing sun.
