When things are difficult, in dharma practice and in life, our tendency may be to doubt ourselves. This self doubt - and doubt in dharma practice - is a profound impediment to our ability to move forward as dharma students. For this reason, it's essential that we learn to be mindful of doubt and to see into its empty nature. In this talk, given on March 23, 2008, Peter Doobinin describes how we practice this important mindfulness. The talk was givein at the Downtown Meditation Community Sunday Night Meditation class.
