Matsya Purana — The Advent of Narasiṃha and Hiraṇyakaśipu’s Weapon-Assault
सर्वास्त्राणामथ ज्येष्ठं दण्डमन्त्रं सुदारुणम् कालचक्रं तथाघोरं विष्णुचक्रं तथा परम् //
sarvāstrāṇāmatha jyeṣṭhaṃ daṇḍamantraṃ sudāruṇam kālacakraṃ tathāghoraṃ viṣṇucakraṃ tathā param //
Then (is named) the foremost among all weapons—the dreadfully fierce Daṇḍa-mantra; also the terrible Wheel of Time (Kāla-cakra), and, supreme above all, the Wheel of Viṣṇu.
By invoking Kāla-cakra, the verse points to Time as an overpowering cosmic force that governs dissolution and transformation; Viṣṇu’s chakra is presented as the supreme divine power that transcends and controls even time-bound terror.
It frames protection as a dharmic duty: rulers and householders are to uphold order through righteous restraint (daṇḍa) and spiritual safeguards, recognizing that ultimate protection is aligned with Viṣṇu’s cosmic authority rather than mere human force.
Ritually, it functions as a naming/recitation of potent astras used for rakṣā (protective rites); such invocations commonly accompany consecrations, boundary-protections, and temple or household protective procedures in Purāṇic practice.
