Matsya Purana — The Burning of Tripura: Maya’s Triple Fortresses and the Boon that Leads to S...
तस्यैव कृत्यमुद्दिश्य तेपतुः परमं तपः विद्युन्माली च बलवांस् तारकाख्यश्च वीर्यवान् //
tasyaiva kṛtyamuddiśya tepatuḥ paramaṃ tapaḥ vidyunmālī ca balavāṃs tārakākhyaśca vīryavān //
With that very aim in view, they undertook the highest austerities (tapas)—Vidyunmālī, mighty in strength, and the valiant one named Tāraka, endowed with great prowess.
This verse does not address pralaya; it highlights a Purāṇic motif where powerful beings pursue intense tapas to fulfill a specific objective, often leading to cosmic imbalance that later requires divine intervention.
Indirectly, it contrasts disciplined austerity used for self-mastery with austerity used for domination; the ethical implication in Purāṇic teaching is that power gained through tapas should be aligned with dharma rather than personal or destructive aims.
No Vastu/temple-building or ritual procedure is specified in this verse; the only ritual element is the general act of performing severe tapas (austerity) as a spiritual practice.
