This item, written by Christian author Norman Vincent Peale and e-mailed to me today by Lama Surya Das on his Weekly Words of Wisdom post, could have easily been taken from the writings of Vietnamese Zen monk Thich Nhat Hanh:
The way to happiness:
Keep your heart free from hate, your mind free from worry.
Live simply, expect little, give much.
Forget self, think of others.
Try this for a week
and you will be surprised.
