“In November of 1960, seven months before his death, C. G. Jung suffered what he called “the lowest ebb of feeling I ever experienced.” He explained the sentiment in a letter to Eugene Rolfe:

I had to understand that I was unable to make the people see what I am after. I am practically alone. There are a few who understand this and that, but almost nobody sees the whole… I have failed in my foremost task: to open people’s eyes to the fact that man has a soul and there is a buried treasure in the field and that our religion and philosophy are in a lamentable state.

… He has not been wholly understood.”
