The Dalai Lama, a lifelong champion of non-violence on Saturday candidly stated that terrorism cannot be tackled by applying the principle of ahimsa because the minds of terrorists are closed.

"It is difficult to deal with terrorism through non-violence," the Tibetan spiritual leader said delivering the Madhavrao Scindia Memorial Lecture here.

He also termed terrorism as the worst kind of violence which is not carried by a few mad people but by those who are very brilliant and educated.

"They (terrorists) are very brilliant and educated...but a strong ill feeling is bred in them. Their minds are closed," the Dalai Lama said.

He said that the only way to tackle terrorism is through prevention. The head of the Tibetan government-in-exile left the audience stunned when he said "I love President George W Bush." He went on to add how he and the US President instantly struck a chord in their first meeting unlike politicians who take a while to develop close ties.
