I can't remember the name of this book I read in college and I'm wondering if people can help me. The book is about a white man who travels India searching for a guru. He eats alot of LSD and Mescaline on his journey. The middle of the book collects the drawings he did during that time mostly under the influence of drugs. In the copy I had, the middle section full of illustrations was printed on brown paper while the rest of the book was printed on normal paper. I know that all sounds very strange but I'd like to be reunited with this book. It's quite good and I'm wondering if anyone has read it or knows the name. Thanks in advance for any useful contributions.
