Matsya Purana — Description of Atri’s Hermitage: Sacred Grove Planning
सदोपगीतभ्रमरसुरस्त्रीसेवितं परम् सर्वपापक्षयकरं शैलस्येव प्रहारकम् //
sadopagītabhramarasurastrīsevitaṃ param sarvapāpakṣayakaraṃ śailasyeva prahārakam //
Supreme indeed is that place (or observance), ever filled with the humming of bees and attended by celestial maidens; it brings about the destruction of all sins, striking them down like a blow upon a rock.
This verse does not discuss Pralaya directly; it focuses on purification (sarva-pāpa-kṣaya) gained through a supremely meritorious sacred place or observance.
It supports the Purāṇic ethic that rulers and householders should pursue public and personal purification through dharmic acts—pilgrimage, worship, and maintaining sacred spaces—since such acts are said to eradicate sin and strengthen moral order.
The emphasis is ritual and sacred-geographical rather than architectural: a sanctified environment (evoked by bees’ constant hum and divine attendance) is portrayed as exceptionally purifying, implying the importance of maintaining a consecrated, worship-ready precinct.
