In plain words
His crown bears a garland of many-coloured flashing gems; the streak of the moon gleaming on that crown is his ornament; ornament itself is his sole ornament. He is the cause of the destruction of Bhava, worldly existence. That Lord of the Gaṇas, the son of Īśāna, I praise.
Close to the Sanskrit
Him whose crown bears a garland of gems flashing in many colours; him whose ornament is the streak of the moon gleaming upon that crown; him whose one ornament is ornament itself; him who is the cause of the destruction of Bhava—him, the Lord of the Gaṇas, the son of Īśāna, I praise.
