Matsya Purana — The Madana-Dvādaśī Vow and the Birth of the Maruts
तदा दितिर् दैत्यमाता ऋषिरूपेण सुव्रता फलाहारा तपस् तेपे कृच्छ्रं चान्द्रायणादिकम् //
tadā ditir daityamātā ṛṣirūpeṇa suvratā phalāhārā tapas tepe kṛcchraṃ cāndrāyaṇādikam //
Then Diti—the mother of the Daityas—steadfast in her vows, assumed the manner of a sage. Living on fruits, she performed austerities, observing severe disciplines such as the Kṛcchra penance and rites like the Cāndrāyaṇa.
This verse is not about Pralaya; it highlights tapas (austerity) and expiatory vows as a spiritual force shaping lineage and destiny in the Purāṇic worldview.
It underscores disciplined observance (vrata), restraint in diet, and recognized penances (like Kṛcchra and Cāndrāyaṇa) as dharmic tools for purification—principles that also guide householders and rulers in self-governance and ethical repair.
The significance is ritual rather than architectural: it names formal penances—Kṛcchra and Cāndrāyaṇa—well-known in Dharmaśāstra/Purāṇic practice as structured rites of austerity and expiation.
