If we look at the world around us, we see that we are conditioned to not listen deeply. Because isn't that what silence is? It's a listening, a deep wordless listening.
There is nothing mind can do that cannot be better done in the mind's immobility and thought-free stillness. When mind is still, then truth gets her chance to be heard in the purity of the silence.
When you inquire 'Who am I?' if you are honest, you'll notice that it takes you right back to silence instantly. The brain doesn't have an answer, so all of a sudden there is silence.
