In his teenage years, he became a kabirpanthi of the Branch of Mokama Ghat, Patna, and was a practising vegetarian. When his wife died in 1959 due to injury caused by falling from a mountain, he decided to carve a path of 110 m long (360 ft), 9.1 m (30 ft) wide, and 7.7 m (25 ft) deep through a ridge of hills using only a hammer and chisel. After 22 years of work, Dashrath shortened travel between the Atri and Wazirganj blocks of Gaya town from 55 km to 15 km. He traveled to New Delhi to get recognition for his work and was rewarded by then Chief Minister of Bihar, Nitish Kumar. In 2016, Indian Post issued a postage stamp featuring him.
