Recorded in London, England on July 4, 2019, Brad Warner introduces his book Letters to a Dead Friend About Zen. The book is a series of letters to Brad’s childhood friend Marky who died in 2014. Brad wants to tell his friend everything he never said, to explain Zen, “this crazy philosophy and weird meditation practice I do every day.” In this episode Brad read a new letter to Marky (not from the book) on the subject of "Beginner's Mind" in Zen Buddhist practice.
