Nārāyaṇa-kavaca — The Armor of Lord Nārāyaṇa
त्वं यातुधानप्रमथप्रेतमातृ- पिशाचविप्रग्रहघोरदृष्टीन् । दरेन्द्र विद्रावय कृष्णपूरितो भीमस्वनोऽरेर्हृदयानि कम्पयन् ॥ २५ ॥
tvaṁ yātudhāna-pramatha-preta-mātṛ- piśāca-vipragraha-ghora-dṛṣṭīn darendra vidrāvaya kṛṣṇa-pūrito bhīma-svano ’rer hṛdayāni kampayan
O best of conchshells, Pāñcajanya in the Lord’s hand, you are ever filled with the breath of Śrī Kṛṣṇa. Therefore your dreadful roar makes the hearts of enemies—Rākṣasas, pramatha spirits, Pretas, Mātās, Piśācas, and brahmaṇa-ghosts of terrifying gaze—tremble and flee.
In the Nārāyaṇa-kavaca (Bhāgavatam 6.8), the devotee prays for the Lord’s fearsome protective presence to drive away harmful beings like pretas and piśācas and to make hostile forces flee.
It appears within the Nārāyaṇa-kavaca, a protective prayer taught for Indra’s safety; Śukadeva narrates it to show how remembrance of the Lord acts as divine armor against dangers and enemies.
Cultivate daily God-remembrance—through prayer, mantra, and sāttvika living—so the mind becomes “filled with the Lord,” reducing fear, strengthening resolve, and protecting one from harmful influences.
