स्वप्नं तु देवदेवस्य न्यवेदयत धार्मिकः ततः शुश्राव वचनं देवतानां समीरितम् //

The righteous one reported the dream to the Lord of gods; then he heard the uttered words of the deities.
It signals a revelatory moment—dreams and divine speech function as omens and guidance; while Pralaya is not named here, the verse fits the Purāṇic pattern where impending cosmic events are announced through such communications.
It highlights dharmic conduct: a righteous person does not act on private visions alone but reports them to the highest authority (Devadeva) and then follows clear, sanctioned instruction—modeling disciplined decision-making for rulers and householders.
No direct Vāstu or temple-building rule appears in this verse; its ritual takeaway is the primacy of authorized revelation (deva-vākya) as the basis for correct observance and subsequent prescribed rites.
