Nirmohi Akharas are the akharas of the followers of Hanuman, the bhakta of Lord Ram.
The main Nirmohi Akhara is thus situated in Ayodhya besides the Sri Ram Janma Bhumi Temple.
This is the place where the saints, mainly the followers of Hanuman, practice for the protection of Dharm.
The members of the Akhara are committed in the cause of Lord Ram as their deity Hamuman was committed for the cause of Lord Ram.
