History of pashupatinath temple

The temple was first established in the 5th century The priests who perform the services at this temple have been Brahmins from South India since the time of Malla king Yaksha Malla. This tradition is supposed to have started by the request of Adi Shankaracharya who sought to unify the different states of Bharatam (Unified India) by encouraging cultural exchange. This procedure is also followed in other temples around India which were sanctified by Adi Shankaracharya.Malla kings honoured the request of Adi shankarachaya as latter being one of the greatest ever Hindu acharyas.
Another interpretation is that Indian priests are stationed at Pashupatinath because when the King passes away, the entire Nepali people are supposed to stop religious services and enter a year long period of mourning and as Pashupatinath needs to be eternally worshiped, Indians were brought in to make sure that Pashupatinath is worshiped even at the time of official mourning.
The unique feature of this temple is that only 4 priests can touch the idol. The priests are always from south India. This tradition is supposed to have started by Sage Shankaracharya in 6th century, ostensibly to stop human sacrifice which was prevalent in that temple. However,this tradition was recently challenged after the historic revolution in Nepal which demolished the monarchy and established democracy where Nepalese priests supported by the anti- Indian Maoists government.There was widespread protests by most Nepalese as they saw this as an intereference in their religion.The Maoists lost power after a few months of this.
