I was new to this sangha and to the patterns of the silent Mahamudra retreat. To my surprise and delight along with chanting, lu jong, walking and sitting, we also sang. Though I had sung one or two of the songs of Khenpo Tsultrim Gyamtso Rinpoche with another sangha, the songs had never had the starring role that they did in this retreat. Such an effective (and indelible) way to be reminded of the teachings!
