People who do vipassana meditation and apply it to their daily life have an entirely silent inner life. Our awareness isn’t what in Thailands version is referred to as the monkey mind that chatters away distracting us from the present. Our inner mind has no voice, it’s what underlies everything we do and it simply is. The mind with a voice is a tool of the real mind, our awareness, but most people confuse their monkey mind with themselves. In Buddhism a great deal of our suffering stems from confusing ourself with that chattering tool. As such, it’s a useful tool for structuring ideas and analyzing, replaying the past and anticipating the future. But a key to happiness is the recognition it’s neither necessary nor sufficient, but is a tool to be used as needed and no more. Our silent inner mind is necessary, sufficient, and forms the exclusive entirety of our existence.
