Matsya Purana — The Strategy to Defeat Tāraka: Pārvatī’s Birth
अकिंचित्करतां यातः करस्ते न विभासते अलं नीलोत्पलाभेन चक्रेण मधुसूदन //
akiṃcitkaratāṃ yātaḥ karaste na vibhāsate alaṃ nīlotpalābhena cakreṇa madhusūdana //
If Your hand were left empty, it would not shine in its full splendor. Therefore, O Madhusūdana, it is fitting that it be adorned with the discus (cakra), radiant like a blue lotus.
This verse does not address Pralaya; it focuses on iconographic theology—how Vishnu’s hand gains splendor through the presence of the Sudarshana Chakra.
Indirectly, it supports dharmic practice by emphasizing correct worship: kings and householders are advised in the Puranas to patronize and maintain proper temple images and rituals, where Vishnu’s attributes (like the chakra) must be depicted accurately.
It signals a pratima-lakshana rule: Vishnu’s image should not be shown with an empty hand; the hand should bear the chakra, aiding correct temple sculpture, consecration (pratiṣṭhā), and devotional visualization.
