For this retreat there is an option to attend the first 3 days only or continue on for the full 7-day retreat. There are no prerequisites to participate in this retreat, but you must be able to attend all the sessions for which you register.
Brief instruction to the practice is provided before every session. Lama Eric Triebelhorn provides detailed instructions about the practice of Shamatha on alternating first Sundays from 9:00am to 12:30 including a question and answer session. These Half-Day Sits happen in odd-numbered months: January, March, May, July, September, and November.
