It cannot be compared with Herman Hesse. Hesse is more abstract and higher planes of philosophy.
One should read Hesse' Demian. In my opinion Demian is better than Das Glasperlenspiel The Glass Bead Game.
One of my observations is modern readership has become Lite version unlike the classical olden days the readership expectations as well as ability to comprehend higher abstract philosophy. It is like Dr. Deepak Chopra's Lite versions of The Gita transformed to light American readership.
