The roles we play in each other's lives are only as powerful as the trust and connection between us--the protection, safety, and caring we are willing to share.
Meditation is valuable for all of humanity because it involves looking inward. People don't have to be religious to look inside themselves more carefully. It is constructive and worthwhile to analyze our emotions, including compassion and our sense of caring, so that we can become more calm and happy.
Look at our culture. Look at the computer-enhanced people we compare ourselves to. Look at the expensive cars and trinkets we're all supposed to have. Look at how many people are wrapped up in that! Imagine how much money and worry we'd save ourselves if we stopped caring what kind of car we drove! and why do we care? perfection. But there is no such thing, is there? And if there is, then everyone is perfect in their own way, right?
The empty mind - the pure mind - is not a blank, zero-land, where you're not feeling or caring about anything. It's an effulgence of the mind. It's a brightness that is truly sensitive and accepting. It's an ability to accept life as it is. When we accept life as it is, we can respond appropriately to the way we're experiencing it, rather than just reacting out of fear and aversion.

The modern world has far too little understanding of the art of keeping young. Its notion of progress has been to pile one thing on top of another, without caring if each thing was crushed in turn. People forgot that the human soul can enjoy a thing most when there is time to think about it and be thankful for it. And by crowding things together they lost the sense of surprise; and surprise is the secret of joy.
