I'm on this Soto Zen list and every so often someone posts the question: "Why do you practice Zazen?" Well, that question has be echoing in my head the past few days and this morning the answer came to me in the following quote from Thich Nhat Hanh:
"If we are peaceful, if we are happy, we can blossom like a flower, and everyone in our family, our entire society, will benefit from our peace."

~ Thich Nhat Hanh in Being Peace

Today I practice Zazen to be Peace. When I sit, I feel it. Peace. It's there, always, I just need to sit and let go of everything else. When I do this it just feels right.
