"Now everything changed. My childhood world was breaking apart around me. My parents eyed me with a certain embarrassment. My sisters had become strangers to me. A disenchantment falsified and blunted my usual feelings and joys: the garden lacked fragrance, the woods held no attraction for me, the world stood around me like a clearance sale of last year's secondhand goods, insipid, all its charm gone. Books were so much paper, music a grating noise. That is the way leaves fall around a tree in autumn, a tree unaware of the rain running down its sides, of the sun or the frost, and of life gradually retreating inward. The tree does not die. It waits." _ Hermann Hesse
One of the major themes is the existence of opposing forces (good and evil) and the idea that both are necessary using the God Abraxas as a Symbol through the story.
