‘Mata Bala Sundari Devi’ is the Kul Devi of ‘Gulerias’.
The original Bala devi temple came under the flood plains of the Pong Dam (which was constructed between 1961 to 1974). While the temple still exists, it led to an alternative temple being constructed for ‘Kul devi’ in Harsar which has the original murti’s now.
Some pictures below of the original and new Kul Devi temple.
