These are ELEVEN SMOKING GUNS declaring that Seth would never communicate thru someone else. You and others ignore his and Jane's own words and explanations. He explained that people would use his name as a symbol for their own inner communications--and that this is common and understandable re Seth readers.
I’ve added the CAPS for emphasis only:
Seth (Session 876, from God of Jane): "A woman wrote that she was involved with. . . correspondences in which I was communicating with her, and she was certain that this would prove beyond a doubt my own independent nature, since I [would have given] messages to another medium besides Ruburt. The woman was quite convinced of that.
"Other people have written that I have given them such messages. Another woman dreamed of me, and had an experience in which a child was definitely healed. Now, I did not communicate with those women—but their belief in me helped each of them use certain abilities. One woman has done some writing—not very good—but still, those abilities came to the fore. The other woman was able to use her own healing abilities.
Jane (Ch.9, Seth Material): “Mrs. Brian had a terrific headache while reading the article (about Seth); suddenly she thought she felt Seth's presence. An inner voice, presumably Seth's, told her that she had been feeling sorry for herself that she must stop brooding over her health at once, get up, and go out for a walk. If so, she would improve at once....
“We asked Seth about the incident. In this case, he said, Mrs. Brian had used him as a symbol of her inner self, or supraconsciousness, to deliver help and healing influences as well as advice. The experience helped the woman to use her own abilities, and the idea of Seth enabled her to activate her own healing forces.”
Jane (Seth Material; Ch.9): "Several people have told me that Seth communicated with them through automatic writing, but Seth denies any such contacts, saying that his communications will be limited to his work with me, in order that the INTEGRITY of the Seth Material be preserved."
Seth (ESP Class, 4-17-73): “If you are quick, and if you are intuitive, and if you are courageous, and if some evening you listen to my voice in the proper mood, then you can follow yourself to the heart of yourself, using the voice as a road or vehicle.”
Seth (Session 463): It is quite natural that others...who are experimenting should go through a stage in which it seems to them they are receiving information from me. Suggestion operates, and any trance deeper than ordinary for them can be interpreted in these terms. He (Ruburt) should understand this, and explain it simply to his students.”
Seth (ESP Class, 12-19-72): “Seth Speaks should be called You Speak and You Speak and You Speak. So listen to yourselves.
Jane (from Dreams, Evolution, & Value Fulfillment--Essay 5, 4-18-82): “And--very troublesome to me--came the repeated news that various people were ‘speaking for Seth’ publicly, and charging hefty-enough fees. I felt that my work was being CONTAMINATED, and more, I was annoyed and disappointed by those readers who could apparently be so taken in by those other Seths. As he has said so many times, SETH SPEAKS ONLY THROUGH ME, TO PROTECT THE INTEGRITY OF THE MATERIAL. AND IT IS INDEED THAT CONTRACT BETWEEN HIM AND ME THAT ALWAYS ASSURES YOU OF THE AUTHENTICITY OF SETH'S WORK...”
Seth (Session 454): “My friend here, Ruburt, is my mouth, and speaks for me...I WILL NEVER SPEAK THROUGH ANYONE OTHER THAN RUBURT, simply because there must never be any doubt of the origin of the Seth material.”
Seth (Session 463): "Now, when you see what Ruburt can do occasionally, and the troubles I can have with distortion, then you can be sure that I WOULD NOT DOUBLE OR TRIPLE THE CHANCES FOR DISTORTION BY ATTEMPTING TO SPEAK THROUGH ANYONE ELSE.
Seth (Session 510): "While MY COMMUNICATIONS WILL COME EXCLUSIVELY THROUGH (JANE) AT ALL TIMES, to protect the integrity of the material...”
Seth (Session 15): "Joseph, your part in these sessions is extremely important. Without your participation they could not have begun, nor could they continue. Because of our past alliances the three of us are closely bound together. However, I need the two of you in order to come through at all."The
