Published only a year after his masterpiece On The Road, Dharma Bums is a visionary look at the debilitating effects of fame and alcohol. It follows Ray Smith (Jack) and Jahy Rider (Gary Snyder) on a buddhist romp through the mountains of the west coast. Contemplating their religions and beliefs and coming to beautiful realisations about the world ("You can't fall off a mountain"), they create the rucksack revolution. A beautiful insight into thought and poetry. A must for anyone who wants to learn to think or expand their mind.
Positive
