I have to say that I believe the GFL exists, but like all of these channellers they have big ideas about their own importance 'Ascended Masters', Lord Sanando, or Commander Haaton. Most of these beings are 5th dimensional although they try to fool us into believing that they are 12th dimensional. They are afraid that we are going to ascend and escape their control, we are their food source, they want us either living in fear, or worshipping them.
George Kavasilas is particularly good on what is going on in the other dimensions, and even he admits that he was fooled by the GFL. He says that there are very few beings from above the 5th dimension talking to us, and that anyone who says they are from 7D + are telling lies.
