Thakur ji as He is fondly called is one of the many forms of Krishna.
Srimad Bhagavatam illustrates an episode wherein Krishna as a young boy lifted Govardhangiri to protect the inhabitants of Brindavan from torrential downpour. The most ancient description of this deity appears in the Girirajakhanda of the Garga Samhita, He has been referred to as Devadaman Shreenath.
Shreenath ji gives darshan on a large black stone with his left hand raised and the right bunged in a fist. The idol is treated like a young boy by the priest and they tend to Him daily with normal activities like bathing, dressing offering bhog called “prasada” and give Him a little rest at regular intervals.
The idol is decorated with fine intricately woven silk cloth with zari work done on them along with lots of gems of antique value. The view of the idol which we get to see after the “Pardha” (curtain) is removed is a spectacular sight that is simply mesmerizing and enchanting.
The legends have it that the image of the Shreenathji was being transferred to safer place from Jatipura (Goverdhan Hill) near Mathura to hid it from the destructive wrath of the Mughal Emperor Aurangzeb. When the image reached a certain spot the bullock carts wheel sank deep in the mud and refused to move further. The accompanying priest realized that this was the chosen spot and the image did not want to travel any further.
Accordingly a temple was built there, the Haveli of Shreenathji as the temple is called, was once a part of Mewar State, which was ruled by Sisodia Kings.
Shreenathji is referred to with the honorific Thakur ji in local area and customarily the name Shreenathji is not uttered as a matter of respect and reverence.
Jai Shree Krishna.
