I really like Jack Kornfield's sentiments and wisdom in "An Opening Bow". It speaks of the benefits of being mindful. Here is an excerpt:
"That is how I began to learn that the true task of spiritual life is not found in faraway places or unusual states of consciousness; it is here in the present. It asks of us a welcoming spirit to greet all that life presents to us with a wise, respectful and kindly heart. We can bow to both beauty and suffering, to our entanglements and confusion, to our fears and to the injustices of the world. Honouring the truth in this way is the path to freedom. To bow to what is rather than to some ideal is not necessarily easy, but however difficult, it is one of the most useful and honourable practices.
To bow to the fact of our life's sorrows and betrayals is to accept them; and from this deep gesture we discover that all life is workable. As we learn to bow, we discover that the heart holds more freedom and compassion than we could imagine."
