Here is the complete 4 CD set from the Summer Solstice Retreat held at Mount Madonna, CA June 2010.  The main topic of Mark's teachings was understanding the modifications of the mind, and why meditation is so extremely critical in becoming free of these modifications long enough to see the ocean of pure consciousness.  

These teachings are truly brilliant and particularly accessible - you will be inspired in your meditation practice like never before.

This is available as a 4 CD set mailed to you, or a digital download.
