It's not that meditation makes us happier or richer or faster. Meditation helps us see at things as they are. Starting with ourselves. When you see yourself as you are, you accept your own uglies and pretties. When you know what you are, you'll know what things you can and cannot do. You’ll understand the consequences of your actions and inaction. You don't hate the world around you because you'd know that you yourself aren't exempt from things that you cannot change.
(And there is much relief in simply not hating or coveting in everysinglemoment of our lives. Wallah.)
Once you see yourself clearer, you'll start seeing the world clearer too. When you see the world clearer, you'll be less surprised by the things that happen in it. It's not passive, antisocial indifference. It's more like, "this is what the world needs, and this is what you can do." So that your hopes become more realistic. And when your hopes are realistic, you'll face less disappointments. With less disappointments comes hope. With hope grows trust in your strengths and limitations. Which helps you accept your purposes in life, in every day, in reading this. And if you can accept your roles, how could you not grow a belief in a more forgiving and understanding afterlife?
(And if you can just consider the possibility of a happy ending, how could you not give it a shot?)
It's not that meditation makes us happier or richer or skinnier. Meditation can't change light-bulbs. It can, however, help you be aware of that broken light bulb and the realistic steps that'll take to fix it.
