Matsya Purana — Lineage of Yayāti through Yadu and the Deeds of Kārtavīrya Arjuna
दत्तमाराधयामास कार्तवीर्यो ऽत्रिसम्भवम् तस्मै दत्ता वरास्तेन चत्वारः पुरुषोत्तम //
dattamārādhayāmāsa kārtavīryo 'trisambhavam tasmai dattā varāstena catvāraḥ puruṣottama //
Kārtavīrya (Arjuna) worshipped Datta, the descendant of Atri. Pleased, Datta granted him four boons, O best of men.
This verse does not discuss Pralaya; it belongs to a dynastic narrative highlighting how royal power arises through the grace of sages and deities.
It emphasizes that a king’s legitimacy and extraordinary capacities are ideally grounded in reverence toward holy teachers (ṛṣis) and disciplined worship, rather than mere force.
No Vāstu or temple-architecture rule is stated directly; the ritual takeaway is the efficacy of ārādhana (devotional propitiation) as a means to obtain sanctioned boons.
