Political life

He was known by several  aliases including Arvind Ji, Vikash Ji, Sujeet Ji and Nishant. Singh started student politics in the era of Mahamaya Prasad Sinha and Jayaprakash Narayan movement. He soon entered left-wing politics under the influence of Naxalbari uprising led by Charu Majumdar and Kanu Sanyal. He joined CPI(ML) Party Unity led by Narayan Sanyal and formed a mass organisation Mazdoor Kisan Sangram Samiti () to campaign for land reform and to establish minimum wages for agricultural labourers. Later he became General secretary of Mazdoor Kisan Sangram Samiti and a member of the Central Organising Committee (top functionary body) of CPI(ML) Party Unity. After the merger of CPI(ML) Party Unity, Communist Party of India (Marxist–Leninist) People's War and Maoist Communist Centre of India, a new party Communist Party of India (Maoist) () was formed on 21 September 2004; he became a member of the Central Committee and Central Military Commission.

He was known as the mass organiser and backbone to set up and strategise guerrilla warfare under People's Liberation Guerrilla Army (India) in Indian forests against the imperialist state. He had proposed a new Strategy & Tactics, Critic Document (), to central organising committee of CPI (ML) Party Unity which was accepted as a parallel thought of party line and played a key role in formation of Communist Party of India (Maoist) by unification of several left parties distributed across the country fighting for the same goal.
