I had a question in my mind about sickness and how we become sick. Do we become sick from karma? Do we become sick from our mind? Do we become sick from uncleanliness? How does sickness come upon us? I hadn’t been able to form it into a question that I could actually ask Srila Prabhupada, and as Srila Prabhupada and I were walking along the big main street, Prabhupada stopped, turned to me and said, “Ninety per cent of all sickness is caused by the mind.”
