Matsya Purana — The Legend of Acchodā: Pitṛloka
व्यतिक्रमात्पितॄणां त्वं कष्टं कुलमवाप्स्यसि तस्माद्राज्ञो वसोः कन्या त्वम् अवश्यं भविष्यसि //
vyatikramātpitṝṇāṃ tvaṃ kaṣṭaṃ kulamavāpsyasi tasmādrājño vasoḥ kanyā tvam avaśyaṃ bhaviṣyasi //
Because you have transgressed the ancestral injunctions, you will attain a troubled lineage; therefore, you shall certainly become the daughter of King Vasu.
This verse does not discuss Pralaya; it focuses on karmic consequence and rebirth within a royal genealogy, linking ancestral transgression to a destined birth.
It underscores pitṛ-dharma: honoring ancestral injunctions and rites safeguards family continuity, while violating them is said to lead to hardship in one’s lineage—an ethical warning relevant to householders and rulers alike.
No Vastu or temple-architecture rule is stated here; the ritual implication is indirect—respect for ancestors (pitṛ obligations and śrāddha-type duties) is presented as crucial for familial well-being.
