I admired his creativity to express his feelings of loneliness, sadness, insecurity through his art - drawings, paintings, sculpture etc.
I really appreciated his courage in noting down his memories about his experience of severe neurosis, psychosis (?) in a red colored diary Red Book.
I also admired his courage to let have his own thoughts being different than Dr. Freud's. He ventured to publish them and shared them with thinkers around the globe.
I was especially intrigued when I learned that he visited India and was fascinated by Hindu and other religions in the subcontinent.
