dhūpo 'tra guggulaḥ śreṣṭhas tāmrapātrairadhiṣṭhitān saptadhānyasthitānkṛtvā vastragandhānulepanaiḥ //

Ritually, it specifies best-practice upachara: guggulu incense set in copper vessels and arranged on a seven-grain base, with cloth, fragrance, and anointing—details often aligned with temple worship and Vastu-linked purity norms.
