I think all these responses just show that when we do something we truly love, we relax, become more peaceful and are able to drop negative thoughts. After all, who can look at beautiful fabric, feel it under your fingers and NOT respond positively? I believe that quilting, for US, releases an enzyme in our brains that relaxes our soul because we love it so. Joy shows up no matter what else is going on.
The Bible says a merry heart doeth good like a medicine and whether you believe the Bible or not, it sure is a sound statement.
