SILENCE does wonders for the mind. Outside or in the mind, reward is great both ways.
For long stories of anger, blame, criticism or gossip, silence could be the answer for listeners, where speaking could be like adding more flames to FIRE.
Minimal use of words could be a great way to observe various thoughts. Also silence is anything but boring, with a nice opportunity to be in a good LIGHT feeling.
And words coming out from a still MIND would also carry more meaning and enthusiasm.
