One of the most important ceremonies which is done in this place is Nagaprathista, it's done by the people who have sarpa dosha in their horoscope. Here the devotees come and pray to the lord asking for a specific boon (such as a child or for marriage). Once the boon is fulfilled, they perform a prathistha. Not all devotees need to do the same, only those devotees who had taken a vow in front of the lord need to do it.
