It is much easier to live mindfully when our bodies are refreshed, nourished, relaxed and in shape. When we eat junk food and do not exercise, our bodies feel sluggish, and so does our mind. A sluggish mind leads to negative thoughts, which contribute to a cycle of malaise, cynicism and lack of fulfillment. Low energy leads to boredom and frustration.
Our bodies are our instruments for interacting with the material world. The more we take care of our instrument, the better it will serve us and contribute to our ability to fulfill our life's purpose.
It is no secret as to what is necessary to keep our instruments in fine tune: Restorative sleep; good nutrition; clean water; exercise and tools for reducing stress (e.g., yoga, meditation, walks in nature, satisfying social interactions).
Let's respect and care for our bodies, so that they can serve us.
