If you are not spending all of your waking life in discontent, worry, anxiety, depression, despair, or consumed by other negative states; if you are able to enjoy simple things like listening to the sound of the rain or the wind; if you can see the beauty of clouds moving across the sky or be alone at times without feeling lonely or needing the mental stimulus of entertainment; if you find yourself treating a complete stranger with heartfelt kindness without wanting anything from him or her... it means that a space has opened up, no matter how briefly, in the otherwise incessant stream of thinking that is the human mind. When this happens, there is a sense of well-being, of alive peace, even though it may be subtle. The intensity will vary from a perhaps barely noticeable background sense of contentment to what the ancient sages of India called ananda - the bliss of Being. Because you have been conditioned to pay attention only to form, you are probably not aware of it except indirectly. For example, there is a common element in the ability to see beauty, to appreciate simple things, to enjoy your own company, or to relate to other people with loving kindness. This common element is a sense of contentment, peace, and aliveness that is the invisible background without which these experiences would not be possible.Whenever there is beauty, kindness, the recognition of the goodness of simple things in your life, look for the background to that experience within yourself. But don't look for it as if you were looking for something. You cannot pin it down and say, "Now I have it," or grasp it mentally and define it in some way. It is like the cloudless sky. It has no form. It is space; it is stillness, the sweetness of Being and infinitely more than these words, which are only pointers. When you are able to sense it directly within yourself, it deepens. So when you appreciate something simple - a sound, a sight, a touch - when you see beauty, when you feel loving kindness toward another, sense the inner spaciousness that is the source and background to that experience.
