Most of Hesse, especially Magister Ludi, are must reads imo. They helped me find my "inner man" if that makes any sense. I was also reading into a lot of wild/hairy myth at the time, so maybe it was a good coincidence, but I've told a lot of women that I think Hesse is a nice portal into a healthy search for a masculine psychology. If there was a male gender studies class, I'd hope that his literature would be included.

He was a patient-student of Jung iirc, you can feel the influence in his writing and meditations. Read Demian.
