In 1573, a local shopkeeper named Lala Ram Dass dreamt of Goddess Bala Sundari, who revealed her disappearance from Devban (UP) and instructed him to build a temple to enshrine her "Pindi" form. The next day, Lala Ram Dass discovered the "Pindi" in a bag of salt brought from Devban. Miraculously, despite selling salt from the bag all day, it remained full. He shared this with Raja Dip Parkash of Sirmour, leading to the construction of the Mata Bala Sundari Temple in Trilokpur.
Raja Dip Prakash inhesitanly agreed and got constructed a temple for the installation of the Divine PINDI of Mata Balasundari jee at Trilokpur. The king invited some artisans from Jaipur [Rajasthan] in 1570 A.D. and a beautiful marble temple dedicated to Goddess Tripur Bala Sundri came by 1573 A.D. In 1823, the temple was renovated by Maharaja Fateh Prakash and by Maharaja Raghubir Prakash in 1851.
The worship of Goddess Bala Sundri became a tradition in the royal family. Over time, the temple was renovated in an architectural style that beautifully blends Indo-Persian elements. Today, the shrine of Bhagwati Bala Sundri attracts over 32 lakh devotees annually. Since the temple's inception, the descendants of Lala Ram Das have been entrusted with performing the main Pooja, maintaining the sacred rituals and traditions.
