Matsya Purana — Kārtavīrya Arjuna’s Solar Boon and the Genealogy from Kroṣṭu to the Yādava Lines
भजमानस्य सृञ्जय्यां बाह्यकायां च बाह्यकाः सृञ्जयस्य सुते द्वे तु बाह्यकास्तु तदाभवन् //
bhajamānasya sṛñjayyāṃ bāhyakāyāṃ ca bāhyakāḥ sṛñjayasya sute dve tu bāhyakāstu tadābhavan //
From Bhajamāna, through Sṛñjayyā and (her line) Bāhyakāyā, the Bāhyakas arose; and for Sṛñjaya, two daughters were then known, called the Bāhyakās.
Nothing directly—this verse is genealogical, recording how a named lineage (Bāhyaka) is traced through Bhajamāna and the Sṛñjaya family line.
Indirectly, it supports the Purāṇic framework where righteous kingship is grounded in lineage memory (vamśa-smṛti); the verse preserves succession and kinship links rather than prescribing duties.
None explicit—no Vāstu, iconography, or ritual procedure is described; the focus is on names and descent within a royal/tribal genealogy.
