"We have a great deal of evidence to show that the RSS is an organisation which is in the nature of a private army and which is definitely proceeding on the strictest Nazi lines... the Nazi party brought Germany to ruins and I have little doubt that if these tendencies are allowed to spread and increase in India, they would do enormous injury to India," the letter read.
The Nehru government had also banned the RSS after Mahatma Gandhi's assasination in 1948 for its alleged role in the killing of the Father of the Nation.
Sardar Patel, too, though having a softer stance towards RSS, had accused it of spreading "communal tension".
At one instance, Patel had attacked the RSS, saying he would not allow any communal organisation to throw the conutry into disintegration.
“We will not allow the RSS or any other communal organisation to throw the country back on the path of slavery or disintegration... I am a soldier, and in my time I have fought against formidable forces… If I feel that such a fight is necessitated for the country’s good, I shall not hesitate to fight even my own son.”
Over the years, the Congress and many of its leaders -- including Pranab Mukherjee -- who claim to follow the secular path, have accused the RSS of peddling communal tensions and disharmony in the society. Thus, it is natural that Congress was "stunned and shocked" when the former Congressman, who himself had been critical of the RSS in the past, accepted the invitation to attend a function of the same organisation.
