In the context of Jainism, Girnar Ji (Mount Girnar) is one of the most important and ancient pilgrimage sites, especially for followers of the Svetambara and Digambara sects. It is located near Junagadh in Gujarat, India.

The management and administration of the Jain temples on Girnar are typically overseen by a "Samiti" or committee, often referred to as the Girnar Jain Derasar Samiti or similar names depending on the sect. These committees are responsible for maintaining the temples, organizing religious events, managing pilgrim facilities, and preserving the sanctity of the site.

There are different committees for the Svetambara and Digambara temples:

• Shri Girnar Jain Derasar Trust (Samiti): Manages Svetambara temples and facilities.
• Shri Digambar Jain Samaj, Girnar: Oversees Digambara temples and related activities.

These committees are usually composed of respected Jain community members. They work to ensure smooth operations of religious activities, upkeep of temples, and welfare of pilgrims.

If you need information about a specific sect’s committee or wish to contact them, you would need to reach out to the respective Jain Samiti or Trust office in Junagadh or at the base of Mount Girnar.
