According to Kashi Khand, Chapter 69, the place where Lord Shiva wore the skin of Gajasur after slaying the latter, was called Rudra Vasam. (Kindly refer to Krithi Vaseshwar).
Once the Lord, in his form as Krithi Vaseshwar, was sitting alongwith Goddess Uma Devi when Nandi offered his prayers and stated that there are 68 places of worship dedicated to Lord Shiva in this holy place. Various idols/Shiv Lings have been brought from several other places and installed in Kashi.
From Trisandhyam Teerth one Ling by name of Triambak has appeared in the Holy city of Kashi, which is called Triambakeshwar. By worshipping this deity, the devotee will get the respect normally given to Lord. (In other words, he will be held in high esteem).
On all India basis there are twelve Jyotirlings and there are twelve important Shiv Lings in Kashi which represent the aforesaid twelve Jyotirlings. The above deity is worshipped as Triambakeshwar (Nashik, Maharashtra).
