Matsya Purana — War of Devas and Asuras; Birth of Aurva Fire; Countering Tamasī Māyā through ...
जनानां वृत्तयस्तिस्रो ये गृहाश्रमवासिनः अस्माकं तु वरं वृत्तिर् वनाश्रमनिवासिनाम् //
janānāṃ vṛttayastisro ye gṛhāśramavāsinaḥ asmākaṃ tu varaṃ vṛttir vanāśramanivāsinām //
For people who live in the householder stage, there are three recognized modes of livelihood; but for us, the superior livelihood is that of those who dwell in the forest-hermitage (the vānaprastha life).
Nothing directly—this verse is ethical instruction about āśrama-dharma, contrasting livelihoods and praising the forest-dweller’s way of life rather than describing cosmic dissolution.
It frames gṛhastha life as having defined, regulated livelihoods, while holding up vānaprastha as a higher ideal—guiding householders (and rulers) to value restraint, simplicity, and eventual withdrawal toward spiritual discipline.
No explicit Vāstu or temple rule appears here; the ritual takeaway is the prioritization of āśrama-based discipline—especially the forest stage associated with austerity, reduced possessions, and contemplative practice.
