Matsya Purana — The Episode of Madhu and Kaiṭabha: Gunas
*श्रीभगवानुवाच किमर्थं हि द्रुतं ब्रूतं वरं ह्यसुरसत्तमौ दत्तायुष्कौ पुनर्भूयो रहो जीवितुम् इच्छथः //
*śrībhagavānuvāca kimarthaṃ hi drutaṃ brūtaṃ varaṃ hyasurasattamau dattāyuṣkau punarbhūyo raho jīvitum icchathaḥ //
The Blessed Lord said: “Why did you speak out that boon in such haste, O best of Asuras? Though life has been granted to you, you now wish once again to live on in secrecy.”
This verse does not directly discuss pralaya; it focuses on moral causality—how rash speech and desire shape one’s fate even after divine intervention (life being restored).
It cautions against impulsive decision-making and poorly considered requests—an ethical guideline relevant to rulers and householders alike: deliberate before asking favors, making vows, or seeking exceptions for personal security.
No Vāstu or ritual procedure is specified in this verse; its takeaway is ethical rather than architectural—avoid haste in vows/boons and recognize that secrecy-driven desires invite scrutiny and consequences.
