Matsya Purana — Agastya’s Origin
*नारद उवाच भूर्लोको ऽथ भुवर्लोकः स्वर्लोको ऽथ महर्जनः तपः सत्यं च सप्तैते देवलोकाः प्रकीर्तिताः //
*nārada uvāca bhūrloko 'tha bhuvarlokaḥ svarloko 'tha maharjanaḥ tapaḥ satyaṃ ca saptaite devalokāḥ prakīrtitāḥ //
Nārada said: Bhūrloka, then Bhuvarloka, Svarloka, and Maharjana; Tapoloka and Satyaloka—these seven are declared to be the divine worlds.
It outlines the vertical hierarchy of the seven higher realms (devalokas), a key cosmological framework used in Purāṇas to describe where beings reside across cycles of creation and dissolution, even though Pralaya itself is not directly described in this verse.
By mapping graded realms from earth to Satyaloka, it implies a moral-spiritual hierarchy: householders and kings cultivate dharma, charity, and sacrifice to attain higher worlds (e.g., Svarloka), while deeper austerity and truth correspond to Tapoloka and Satyaloka—goals that guide ethical governance and disciplined living.
The verse itself is cosmological, but in Vāstu and ritual thought these lokas correspond to cosmic “levels” mirrored in temple symbolism (axis mundi/vertical ascent) and in ritual utterances like the Bhūr-Bhuvaḥ-Svaḥ triad that situates rites within a layered universe.
