Kashi Khand, Chapter 100 states that devotees should undertake religious tours (Yatra) of various deities situated inside the main area of Kashi. This temple has its mention in Kashi Khand.
The Rudra Samhita of the Mahashiv Purana refers to this well-known pilgrimage, also known as the Aapa Stambheshwar Mahadev Temple. He said that Lord Shiva’s elder son Kartikeya erected this shrine. After killing Lord Shiva’s devotee Tadkarsur, Lord Kartikeya became restless, and at his father’s request, he erected this shrine at the scene of the crime.
This temple’s Shivling is approximately 2 feet broad and 4 feet high. The different holy Teerths (Ponds), Koops (Wells), and sites of devotion in Kashi were described by Lord Shiva. Lord Shiva enjoyed describing such locations (Kashi Khand, Chapter 97).
The Aapa Stambeshwar Ling is close to Madhyameshwar. Brahma Gyan is bestowed upon the devotee through this Ling’s worship (ultimate knowledge). This might be interpreted as strong education or study in the modern setting.
