In plain words
May the trident of Śiva protect us—that weapon resting on His fingertips, whetted on the chests of foes, tenderly anointed time and again by the mountain king's daughter, flashing like tongues of fire, destroying every sin, and wholly dedicated to guarding those who taste the joy of devotion to His holy feet.
Close to the Sanskrit
May the trident of the enemy of time—which resides on the tip of the hand, sharpened on the whetstone of enemies' chests, anointed with affection on every occasion by the excellent daughter of the mountain, having a face companion to blazing fire-flames, the destroyer of sin, and whose exclusive nature is protecting those who relish devotion to the holy feet—protect us intensely.
