Our teacher, Thich Nhat Hanh, delivered a guided meditation and talk on 31 March to over 3000 people in Trafalgar Square. His monastic disciples chanted the name of Avalokiteshva, the Bodhisattva of Great Compassion. 

Here’s a recording of the talk and chanting:  http://soundcloud.com/elina-pen/sit-in-peace-with-thich-nhat
