By Swami Harshananda
Sometimes transliterated as: Daivata-linga, Daivata-liGga, Daivata-lingaŚiva, the third deity of the Trinity, is always worshiped as a liṅga, a cylindrical symbol with a spherical top. The word ‘liṅga’ means that Supreme Power into which the whole universe dissolves at the end of creation.
līyate asmin iti liṅgah.
A liṅga can be cala (movable) or acala (immovable). The liṅgas in Śiva temples are always acala. Such acala-liñgas can be of several varieties 4 or 6 or even 9. Daivata-liṅga (also called ‘daivika-liṅga’) is one of them. It might have been established by the gods of heaven from which it has got the name (daiva = related to gods).
It's shape resembles to that of a flame of light. It suggests our mind and hands folded in supplication. It's surface is rugged and contains marks of ṭaṅka (hammer) and śula (spear). There is no brahmasutra mark.
