The druids never used the word awen. Awen is a welsh word. The druids did not speak welsh. duh.
I like the word awen, but it was not used by the druids. It is used by modern Neo pagans, or what we know as hippies with drums. I am fine with the word awen, but trying to say it is a real druid word is just not true. And remember the Taliesin poems were written much latter by Christian Monks, who were trying to convert Irish tribes to christianity, and they did a dam good job of it. Go to the source, not the hippies with drums if you want to be a druid.
