Silence and stillness are not states and therefore cannot be produced or created. Silence is the non-state in which all states arise and subside. Silence, stillness and awareness are not states and can never be perceived in their totality as objects. Silence is itself the eternal witness without form or attributes. As you rest more profoundly as the witness, all objects take on their natural functionality, and awareness becomes free of the mind's compulsive contractions and identifications. It returns to its natural non-state of Presence.
The pause - that impressive silence, that eloquent silence, that geometrically progressive silence which often achieves a desired effect where no combination of words, howsoever felicitous, could accomplish it.
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.
To be silent is not to lose your tongue. On the contrary, it is only through silence that one can discover something new to talk about. One who talked incessantly, without stopping to look and listen, would repeat himself ad nauseam.
