Genjo Marinello Osho gave this Teisho on June 21st, at Chobo-Ji, the first day of Summer Sesshin 2014.  This talk explores Case 1 of the Mumonkan, where master Joshu says "Mu" in response to the question, "Does a Dog have Buddha Nature?" Genjo explores the box of our own making that isolates us from our infinite depth, and how to use our practice to "take a breath of fresh air."
