Volume 4 takes young Siddharta into the forest of Uruvela, where he starts the trials to find his enlightenment. The series continues it's lighthearted, fresh and joyful tone. I love how it highlights the most important bits of Buddha's search for meaning while keeping the story fun and moving along.
I still struggle with the almost total lack of female characters of any weight. Other than that I am really enjoying the series, most particularly the amazing illustration that is filled with dynamism and movement.
