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