I found I was able to relieve people not only of pain but of fear. It's strange how many people suffer from it. I don't mean fear of closed spaces and fear of heights, but fear of death and, what's worse, fear of life. Often they're people who seem in the best of health, prosperous, without any worry, and yet they're tortured by it. I've sometimes thought it was the most besetting humour of men, and I asked myself at one time if it was due to some deep animal instinct that man has inherited from that primeval something that first felt the thrill of life.
