Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O best of conchshells, O Pañcajanya in the hands of the Lord, you are always filled with the breath of Lord Krsna. Therefore you create a fearful sound vibration that causes trembling in the hearts of enemies like the Raksasas, pramatha ghosts, Pretas, Matas, Pisacas and brahmana ghosts with fearful eyes.
