I just checked our library site and it doesn't look like they carry the Seth books anymore.
I saw one book there by a Jane Roberts,"Education by oversoul seven"
Does that sound like one of her books?
I think i read them in the 80's, so i am not sure about that other voice she channeled.
She channeled in the early 60's didn't she?
I surmise she was quite an oddity at that time, but intriguinely fascinating.
What a rush it would have been to sit in on one of her sessions.
