The relationship between the Rashtriya Swayamsevak Sangh a cultural organisation and the political parties?Bharatiya Jana Sangh and the Bharatiya Janata Party is unique in the history of Indian polity. Because of the shared ideology and cadre, the inner working and the interpersonal relationships have been a matter of surmise and conjecture. It has become more so now when the BJP has got an absolute majority to become the ruling party at the centre.

This book depicts the history, foundation and development of this relationship and how this symbiosis has played out over the years.
