At certain times, a silent mind is very important, but 'silent' does not mean closed. The silent mind is an alert, awakened mind; a mind seeking the nature of reality.
Thubten YesheWe completely deny the existence of a self-existent I, or a permanent, independent soul. Every aspect of your body and mind is impermanent: changing, changing, changing.
Thubten YesheThe fact is that when you are in a clean, clear state of mind you will be free to pay full attention to what you are doing and you will therefore naturally do it well. Problems come when you are not living in a natural state of mind. Then, no matter what you are doing your mind will be on something else.
Thubten Yeshe
