So what is emptiness? It is simply this unfindability.
When we look for the flower among its parts, we are confronted with the abscence of such flower. That absence we are confronted with is the flower's emptiness. But then, is there no flower? Of course there is.
To seek for the core of any phenomenon is ultimately to arrive at a more subtle appreciation of its emptiness, its unfindability.
His Holiness the Dalai Lama
Don't bring your materialistic way of life to your Dharma practice. It doesn't work. Before meditating, check and correct your motivation. If you do this, your meditation will become much easier and more worthwhile, and your right action will bring realizations.
You don't need to be hungry for realizations, grasping, "Oh, if I do this, will I get some fantastic realizations?" You don't need expectation; realizations will come automatically. Once you've set your mind on the right path, realizations will come of their own accord.
