vedoktairāgamoktairvā maṃtrairarghaṃ pradāpayet | arcitaḥ savitā yena tena trailokyamarccitam
ヴェーダ、あるいはアーガマ（Āgama）に説かれる真言によって、アルギャ（arghya、水の供献）を捧げよ。サヴィトリ（Savitṛ）を礼拝する者は、三界を礼拝したも同然である。
Traditional Purāṇic narrator (contextual instruction within Dharmāraṇya Khaṇḍa; speaker not explicit in the snippet)
Scene: A devotee offers arghya with cupped hands; the water-stream rises as a luminous arc into the sun, which contains within it faint three-tiered worlds (heaven, earth, nether) as symbolic spheres.
FAQs

The verse is a universal mahātmya of Sūrya-upāsanā rather than a localized tīrtha description.
Offer arghya using mantras from either Vedic sources or Āgamic sources.
