Mutual promises
I asked Unmilan to stay in New York for several months to make exercise machines for me. I told him he could stay on one condition — that he had to make me very strong. So he made me many exercisers. A few days ago, as I was going down the stairs in my house, I told him: “You have made me strong. Since you have kept your promise, it is up to me to keep my promise and make you spiritually strong.”— December 1985
