Watch what you allow into your mind. People are completely unaware; they go on reading everything and anything, they go on looking at the tv, any silly stupid thing. They go on listening to the radio, they go on chitchatting, chattering with people, and they are all pouring rubbish into each other's heads. Rubbish is all that they have.
Avoid such situations in which you are unnecessarily burdened with rubbish. You already have too much as it is, you need to be unburdened of it. And you go on collecting it as if it is something precious.
Talk less, listen only to the essential, be telegraphic in talking and listening. If you talk less, if you listen less, slowly slowly you will see that a cleanliness, a feeling of purity, as if you have just taken a bath, will start arising within you. That becomes the necessary soil for meditation to arise. Don't go on reading all kinds of nonsense.
