Why has the RSS called for dialogue with Pakistan?

The story so far:

Last week, Dattatreya Hosabale, the second in command in the Rashtriya Swayamsewak Sangh (RSS), the ideological mothership of the Bharatiya Janata Party (BJP), said in an interview to news agency Press Trust of India (PTI) that India should persist with attempts at a dialogue with Pakistan. His statement triggered reactions from Pakistan, leaders of political parties in Jammu and Kashmir (J&K), India’s former Chief of Army Staff, and from the Opposition.
