Matsya Purana — Manvantaras
निवृत्तिसमकाले तु पुराणं तदचेतनम् क्षेत्रज्ञेन परिज्ञातं भोग्यो ऽयं विषयो मम //
nivṛttisamakāle tu purāṇaṃ tadacetanam kṣetrajñena parijñātaṃ bhogyo 'yaṃ viṣayo mama //
At the time of withdrawal (nivṛtti), the body—ancient and insentient—is clearly understood by the Kṣetrajña (the Knower of the Field, consciousness) as: “This object of experience is to be enjoyed by me.”
It does not describe cosmic Pralaya directly; it teaches an inner “withdrawal” (nivṛtti) where the Self (kṣetrajña) recognizes the body as insentient and merely an object of experience.
It supports ethical self-governance: even while ruling or managing household life, one should cultivate discernment that pleasures and duties belong to the field of experience (viṣaya), while the conscious Self remains the knower—reducing attachment and promoting dharmic restraint.
No Vāstu or ritual procedure is stated; the focus is philosophical—distinguishing the conscious knower (kṣetrajña) from the insentient body (acetana) and its objects (viṣaya).
