It’s a very interesting 14 minutes talk on practice of tantra and dissolving of ego consciousness. It’s part 4 of ‘Explorations of Tibetan Tantra: A Weekend Workshop with Reggie Ray’ (Nov 20 – 22, 2009, Portland, OR) fully available to download at: dharmaocean.org. There is a lot of different audio teachings available on the site so you will need to scroll down a bit to find the rest of the tantra workshop recordings. They are all free.
Me and Anton came across this yesterday at Dharma Mind Open Meditation Group meeting at Anam Cara in Inverness.
