Yoga can change your life. That’s what local author John P. Vourlis found when 20 yoga students from Cleveland traveled to Nepal to raise awareness about child slavery. His new book, Yoga for Freedom, “recounts their journey of self-discovery in the ancient land of Buddha.” Much of the book is told in the students’ own words. Tonight at 7 at the Yoga Room, several of the travelers, including the author, will read from the tome at a book launch party. Nepali snacks will be served. The book will be available for purchase and for signing. (Niesel)
