Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
अस्त्राणि तेजांसि धनानि धैर्यं सेनाबलं वीर्यपराक्रमौ च सत्त्वौजसां तन्निकरं बभूव सुरासुराणां तपसो बलेन //
astrāṇi tejāṃsi dhanāni dhairyaṃ senābalaṃ vīryaparākramau ca sattvaujasāṃ tannikaraṃ babhūva surāsurāṇāṃ tapaso balena //
Through the power born of austerity, the gods and the asuras came to possess an amassed store of weapons, radiance, wealth, steadfast courage, the strength of armies, and heroic vigor and prowess—indeed, a concentrated abundance of vitality and inner force.
It does not describe Pralaya directly; it teaches a Purāṇic causal principle that tapas (austerity/merit) can generate immense worldly and supra-worldly power—resources that shape cosmic conflicts rather than dissolution itself.
It implies that durable sovereignty is not merely material: weapons, wealth, and armies become truly effective when grounded in dhairya (fortitude) and inner ojas—i.e., disciplined conduct, restraint, and merit, which Rajadharma treats as the hidden foundation of power.
No explicit Vāstu or temple rule appears; ritually, the verse highlights tapas as a force-multiplier—suggesting that disciplined observances and austerity are considered efficacious sources of tejas and ojas in Purāṇic ritual culture.
