This quote what I found doing research on spinning cotton! Apparently Gandhi promoted a contest to create a book sized fiber spinning wheel called a Charkha. It was part of his self-reliance initiative!
“Take to spinning to find peace of mind. The music of the wheel will be as balm to our soul. I believe that the yarn we spin is capable of mending the broken warp and woof of our life. The charkha (spinning wheel) is the symbol for nonviolence on which all life, if it is to be real life, must be based.”
Harijan, April 27, 1947, p. 122
Apparently, Gandhi’s personal charkha was recently sold (11/06/2013) at auction for 100,000 pounds (of what, I don’t know but people seemed excited).
