One nearby room has been made as living room with tables and chairs made in silver, and another regarded as the ShayanKaksha (Bed Room), where a bed, dressing table and table are carved in silver. This shrine opens on a large satsang or prayer hall, where religious discourses and bhajans, (religious songs) are held. Just at the entrance to the main temple, stand an old tree, where devotees tie holy threads for wish fulfillment.
