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 //
“What has been gained, and what is now to be done? By doing what can happiness arise? Devayānī has borne children—yet I have reached youth in vain.”
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.
