The meeting between Modi and Sampath took place before the Prime Minister left for Maharashtra where he addressed various meetings along with Chief Minister Devendra Fadnavis.
Thanking the Prime Minister, Sampath too put out a tweet later in the day and said it was an "honour" to get the chance to meet him.
"Respected Prime Minister Narendra Modiji. It was an honour to meet you and present a copy of my book "Savarkar Echoes from a forgotten past" to you this morning. Your energy, enthusiasm and encouragement are infectious. Thank you very much Sir," Sampath's reply to the Prime Minister on Twitter read.
