Just as the Yajna (sacrificial) fire, its smoke, ashes, and flames, the Soma plant, and the ox that used to carry on its back the wood for the Vedic sacrifice gave place to the conceptions of the brightness of Shiva's body, his tawny matted hair, his blue throat, and the riding on the bull of the Shiva, the Yupa-Skambha gave place in time to the Shiva-Linga.
In the text Linga Purana, the same hymn is expanded in the shape of stories, meant to establish the glory of the great Stambha and the superiority of Shiva as Mahadeva.
