Conch

Oh excellent Conch Pāñcajanya: Blown by Lord Kṛṣṇa you, by your terrific blast, shock the hearts of enemies with convulsions of fear. May you drive away demonic spirits like Yātudhānas, Pramathas, ghosts, Mātṛkā (female spirits posing as mothers) Piśācas, Brahmarākṣasas, and other evileyed spirits.
