Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
एकैकमनुरक्ताश्च चक्रवाकमिव ध्रुवम् अनामया ह्यशोकाश्च नित्यं मुदितमानसाः //
ekaikamanuraktāśca cakravākamiva dhruvam anāmayā hyaśokāśca nityaṃ muditamānasāḥ //
Each remains devoted to the other, steadfast like the cakravāka pair. They are free from illness and sorrow, and their hearts are ever cheerful.
This verse does not discuss Pralaya; it focuses on dharmic well-being in domestic life—mutual devotion, health, and freedom from sorrow.
It supports Gṛhastha-dharma: a stable household is marked by mutual fidelity and emotional steadiness, producing health, peace, and social harmony—ideals a king should also protect and promote among citizens.
No Vāstu or ritual procedure is stated directly; the takeaway is ethical: inner harmony and steadiness are treated as auspicious conditions for a flourishing household.
