Matsya Purana — Yayāti in Amarāvatī-like Splendor: Devayānī Installed
किं प्राप्तं किंच कर्तव्यं कथं कृत्वा सुखं भवेत् देवयानी प्रसूतासौ वृथाहं प्राप्तयौवना //
kiṃ prāptaṃ kiṃca kartavyaṃ kathaṃ kṛtvā sukhaṃ bhavet devayānī prasūtāsau vṛthāhaṃ prāptayauvanā //
किं मया लब्धं, किं वा कर्तव्यमधुना? केन कर्मणा सुखं स्यात्? देवयानी पुत्रवती जाता; अहं तु व्यर्थं यौवनं प्राप्तवती॥
Nothing directly—this verse belongs to a human, ethical-psychological narrative (ākhyāna) focused on duty, desire, and the pursuit of happiness rather than cosmic pralaya.
It frames a classic dharma-question: “What is to be done for true happiness?” In Matsya Purana’s narrative ethics, sukha is not merely youth or sensual opportunity; it is tied to right action (kartavya) and the socially consequential outcomes of life (e.g., marriage, progeny, duty).
None is explicit here; the verse is a personal lament within a royal-genealogical storyline, not a Vastu Shastra or ritual-procedure passage.
