This video, entitled ‘Seeking The Buddha Through History' was the first in the series, by Vishvapani. It’s available as a transcript on his new blog www.wiseattention.org - dedicated to Buddhism, mindfulness and ethics.
Other talks from the Convention are available from VideoSangha at www.videosangha.net/playlist/Combined-Convention-2011 for the Combined Convention and www.videosangha.net/playlist/Mens-Convention-2011 for the Men's Convention. Unfortunately there were technical problems that meant that none of the talks on the Women's Convention were video-recorded.
