Stillness Speaks by Eckhart Tolle (Page 4):

The equivalent of external noise is the inner noise of thinking.   The equivalent of external silence is inner stillness.

Whenever there is some silence around you -- listen to it.  That means just notice it.  Pay attention to it.  Listening to silence awakens the dimension of stillness within yourself, because it is only through stillness that you can be aware of silence.

See that in the moment of noticing the silence around you, you are not thinking.  You are aware, but not thinking.

When I started looking as Shiflut and Kavanah, Hacah and Damam, I thought of Kavanah and Damam as external, leading to external actions, and Shiflut and Hacah as internal, leading to internal words.  When I first read this entry, I wasn't sure what to think.  Digging deeper, I realized I had it backwards.  Lowliness and Silence, along with words, are external, because they relate to things external.  Intention and Stillness, along with actions, are internal, because they relate to things internal.

Awareness is Kavanah.  Awareness of Silence, Kavanah of Hacah, brings us to Damam.  Kavanah of Hacah is not Damam, but it leads us to Damam.

Stillness Speaks by Eckhart Tolle (Page 6):

Silence is helpful, but you don't need it in order to find stillness.  Even when there is noise, you can be aware of the stillness underneath the noise, of the space in which the noise arises.  That is the inner space of pure awareness, consciousness itself.

You can be aware of awareness as the background to all your sense perceptions, all your thinking.  Becoming aware of awareness is the arising of inner stillness.

Awareness of Awareness is Kavanah of Kavanah.  Kavanah of Kavanah is Stillness, Damam.  As we become Intentional, we become aware that we are Intentional.  This brings us to Damam, Stillness.

Kavanah of Shiflut, Awareness of Lowliness, is Hacah, Silence, for when we are Aware of and Intentional in remembering we are Lowly, we know our own words will never be enough, so we step into Hacah, and are Silent, waiting for words that are not our own.  This is the essence of Prophecy.
