From Thich Nhat Hanh, Living Buddha, Living Christ (1995):

Meditation is not a drug to make us oblivious to our real problems. It should produce awareness in us and also in our society. For us to achieve results, our enlightenment has to be collective. How else can we end the cycle of violence? We ourselves have to contribute, in small and large ways, toward ending our own violence. Looking deeply at our own mind and our own life, we will begin to see what to do and what not to do to bring about a real change.
