The Empty Glasses

There are some glasses on a table. Some of the glasses are partially filled with different kinds of liquid stuff. Some are already filled to the fullest. There are only a couple of glasses which are empty. But one of them is clean while the other is not washed properly. Someone comes with a new wine to fill into the glasses. Naturally, he has poured the wine into the empty and clean glass only. If he may pour some wine to the other glasses as well the contents of the glasses will not be the same pure wine, but rather it is going to be a mixture of the wine and whatever contents already there in the glasses.  For us to be filled with new energy and understanding, we have to be empty and pure, and that is why Meditation is important: to make us empty and clean.
