"His (Vivekanandaji's) thoughts are as useful today as they used to be then. His thoughts throw light on India's development as well as the world," Bhagwat said.
He was addressing a concluding session of the two-day national seminar organised by the Bhartiya Vichar March, marking the 150th birth anniversary of Swami Vivekananda.
"In today's fast-paced world, one feels like reviewing 150-year-old thoughts of Swmi Vivekananda as they continue to be as relevant as they were then," the RSS chief said.
Bhagwat said even the world acknowledges that thoughts of Swamiji brought about a change in the thought process of the people.
