Pranayama, Chi, breath, all names for the life giving force. I often remind my students that life begins with a breath and ends with a breath. Think about that the next time you effortlessly take a breath. We don't think about the breath because it is so natural for most of us.
Yesterday I observed one of our four legged family members take his last breath and his soul leave his body. I was reminded again that our bodies, while of colossal importance, are only temporary "houses" for our souls. When you witness death, it is sad but also peaceful, especially if someone or something has been suffering. We had a wonderful life with our dog, Dizzy, and I don't regret letting him go even though we are grieving his loss.
I hope that the human race will progress to the point that we can allow each other a dignified death when the time comes, rather than when a hospital or doctor determines we are ready.
