Matsya Purana — Yadu Lineage
यज्ञस्यावभृथे दृश्यौ शण्डामर्कौ तु दैवतैः एते देवासुरे वृत्ताः संग्रामा द्वादशैव तु //
yajñasyāvabhṛthe dṛśyau śaṇḍāmarkau tu daivataiḥ ete devāsure vṛttāḥ saṃgrāmā dvādaśaiva tu //
At the concluding bath (avabhṛtha) of the sacrifice, Śaṇḍa and Amarka were seen by the gods. These were the Deva–Asura conflicts—twelve battles in all—said to have taken place.
This verse does not describe Pralaya; it focuses on yajña-ritual context (the avabhṛtha) and recalls Deva–Asura battles counted as twelve.
It emphasizes the proper completion of sacrifice through the avabhṛtha rite—relevant to householders and kings who sponsor yajñas—linking ritual order with cosmic order even amid conflict narratives.
Ritually, it highlights the avabhṛtha, the concluding purificatory bath that marks the formal completion of a yajña; no Vāstu or temple-architecture rule is directly stated in this verse.
