Attacking Congress, Rajnath Singh said its policy has been of divide and rule.
The BJP Chief also attacked the Congress for accepting the division of the nation on religious lines which Muslim leaders like Maulana Azad never accepted, saying it was "communal".
He accused Congress of indulging in riots and cited Rajiv Gandhi's reported words after Indira Gandhi's assassination -- "When a big tree falls, the earth shakes".
For BJP, the party chief said, the country's Constitution is its religion and Hindutva is nothing but a way of life in which the world is a family and it "loves" Muslims.
Singh said Modi has defined secularism as "India first" and called for doing politics of justice and humanity.
