Explanation:

Dashrath Manjhi  also known as Mountain Man, was a laborer in Gehlaur village, near Gaya in Bihar, India. In his teenage years he became a kabirpanthi of the Branch of Mokama Ghat, Patna, and was a practising vegetarian. He was a flag bearer of social justice. When his wife died 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 travelled to New Delhi to get recognition of his work and was rewarded by then Chief Minister of Bihar, Nitish Kumar. In 2016, Indian Post issued a postage stamp featuring him.
