Say you are very thirsty, and the only water you have is a glass of muddy water.
Since you have no other water, you can’t afford to just throw it away. What do you do?
You wait. You give it time to allow the mud to settle. Then you can drink the clear water from the top.
This simple metaphor is surprisingly powerful when you come to meditate. When we first sit down to meditate, our minds are often very busy, straying this way and that way. But give it a while. Let the “mud” settle. As you have been sitting for a while, the mind gets calmer, clearer.
Remember this when you sit. Don’t get discouraged if at first your mind is very busy. Let the mud settle.
