Maat

I came upon this subject:

"The Egyptian concept of Ma’at is one of the sources of the Hermetic monotheistic tradition."

I know about Maat but I have never seen a reference about Maat and Hermetic teachings. I have seen Isis as a ruler, and she is similar to Maat. I would like to know more about this. 

The symbol of the feather has always attracted me and i know a bit but  would like to see your opinion about these matters. 

Also, do you see a connection between Maat and the Power of Justice on CHXIII what about this chapter of Gnosis, the Verb, the Power of Egyptian Speech, and Liberality?, as a Power that frees people from the Torments, by the Power of Hermes Speech Tat ascends to the Ogdoad and latter the Ennead.
