Worship the Lingam of the soul. Sing the praises of the most ancient and wonderful Lingam, the Lingam of the snakes, the Lingam of nine precious stones, the Lingam that emerged from the lotus of His navel. Sing the praises of the Lingam of Ìshvara, the unlimited sovereign Deity, who is all-powerful.
