Os is the long o sound.
Anglo-Saxon Rune Poem (from ragweedforge.com)
The mouth is the source of all language,
a pillar of wisdom and a comfort to wise men,a blessing and a joy to every knight
It seems today is going to be filled with communication, or perhaps great use of communications technology. It also seemed to be a communication of the Gods and wights/spirits to me, as there was a moment this morning during my meditation that a message was a given. Unfortunately I am not quite sure what the message means, but it was one of those moments, when the stillness and silence just suddenly seems loud and not so still.
