Mahatma Gandhi's assassination led to imposition of ban on the RSS and publication work came to a grinding halt. A different strategy was adopted keeping the ban in mind and Nanaji was the brain behind underground publication work by the RSS those days. When the ban was lifted and it was decided to have a political organization, Jana Sangh came into being. Nanaji was asked by Shri Guruji to take charge of Bharatiya Jana Sangh in Uttar Pradesh as party Secretary. Nanaji had worked as RSS pracharak in Uttar Pradesh and his groundwork proved of a great help in organizing BJS at the grass roots. By 1957 BJS had established its units at each and every district in Uttar Pradesh and credit for this goes to the Nanaji who had extensively traveled all over the State.
Soon, BJS became a force to reckon with in Uttar Pradesh. In 1967 BJS became the part of United Legislature Party Government headed by Chaudhary Charan Singh. Nanaji played a crucial role in evolving the alliance as he enjoyed good relations with Charan Singh and Dr. Ram Manohar Lohia. He was successful in bringing leaders of different political background on one platform to give Uttar Pradesh its first non-Congress government.
A political giant, like Chandra Bhanu Gupta, had to face one of the biggest challenges of his life when Nanaji outwitted him not once but thrice. On one occasion, he planned a strategy to defeat the Congress nominee and CB Gupta's favorite in Rajya Sabha. When CB Gupta himself contested elections from Lucknow in 1957, Nanaji crafted an alliance with socialist groups and helped Babu Triloki Singh in registering an impressive win over Gupta. Shri Gupta faced another embarrassment when he was again defeated at Maudaha in Uttar Pradesh.
In Uttar Pradesh BJS gained strength from Deendayalji's margdarhsan, Atalji's oratory skills and Nanaji's organizational work and it emerged as an important player in the State politics. Nanaji always shared good relations not only with his party colleagues but also with his Opponents. Shri CB Gupta, who suffered many humiliating, defeats at the hands of Nanaji, yet he continued to have great respect for him and called him 'Nana Phadanvis '. His relations with Dr. Ram Manohar Lohia changed the course of Indian politics. Once he invited Dr. Lohia in BJS karaykarta sammelan where he met Deendayalji for the first time and this association brought the BJS closer to socialist parties in exposing the Congress and its misrule.
Nanaji actively participated in Bhoodan Movement started by Vinoba Bhave. By spending two months with Vinoba he was inspired by the success and appeal of the movement. When Jai Prakash Narayan gave the call for" Total Revolution" he responded by giving total support to this movement. When the Janata Party was formed Nanaji was one of its main architects. Janata Party stormed into power by sweeping off the Congress and Nanaji was elected from Balrampur parliamentary constituency in Uttar Pradesh. When he was offered ministerial berth by the then Prime Minister, Shri Morarjee Desai he politely refused it. For him politics was never a career but a mission. He was not the person who would stick to politics or office come what may. Of his own volition he announced his retirement from politics in presence of Jai Paraksh Narain and since then never looked back.
Nanaji is now devoting his entire time to Deendayal Research Institute that he himself established way back in 1969. He established Chitarkoot Gramodya Vishwavidyalaya in Chitrakoot, India's first rural university and was its first Chancellor. NDA Government headed by Shri Atal Bihari Vajpyaee nominated him as an MP in Rajya Sabha in the year 1999 as recognition to his services to the nation.
