Matsya Purana — Tārakāsura’s Austerity and Boon; Mobilization for War; Bṛhaspati’s Fourfold P...
उद्विग्नाश्च सुराः सर्वे तपसा तस्य भीषिताः एतस्मिन्नन्तरे ब्रह्मा परमं तोषमागतः //
udvignāśca surāḥ sarve tapasā tasya bhīṣitāḥ etasminnantare brahmā paramaṃ toṣamāgataḥ //
All the gods became distressed, frightened by the power of his austerities; in the meantime, Brahmā attained the highest satisfaction (and was well pleased).
This verse does not directly describe pralaya; it highlights the Puranic principle that intense tapas generates a cosmic potency that can unsettle the devas, prompting Brahmā’s intervention or approval.
Indirectly, it affirms that disciplined self-control (tapas) has real spiritual efficacy; for kings and householders in the Matsya Purana’s ethical framework, regulated vows, restraint, and dharmic observances are portrayed as powerful supports for order and merit.
No Vāstu or temple-architecture rule appears in this verse; its ritual takeaway is the acknowledged potency of tapas as a sanctioned spiritual practice that draws divine attention and results.
