FAQs
Even cosmic powers, when intensified through tapas (disciplined austerity), become overwhelming—teaching reverence for dharma-governed restraint.
The broader frame is Kāśī in the Kāśī Khaṇḍa, though this verse itself focuses on Sūrya’s cosmic heat rather than naming a specific tīrtha.
No explicit ritual (snāna, dāna, japa) is stated here; the theme is tapas as a cosmic force.
