Seth: Jane was to channel for 40 years

 "Now. Ruburt’s abilities were so strong since childhood that he feared using them, and so I am quite used to that development. On the other hand, I wanted someone with a strong-enough ego structure to contain what will amount to... 40 years of mediumistic experience. I needed a personality who would be able to maintain psychological stability.

Now, I have maintained psychological stability for centuries so I find it not too much to ask that our friend Ruburt maintain it for a mere 40 years. And we expect you to maintain it. We expect you(CW) to maintain it ... and before you get the idea, again, of leaving physical reality before your chores are done, I will give you the boot from the other end.

[... 6 paragraphs ...]

It is a portion that has been physical. It is a portion that can understand your (TM) being overwhelmed with work; it is a portion that can understand your being full with child (SW); it is a portion that can understand the times when you wanted to leave physical reality (CW); it is a portion that can understand the part of you (SB) that wanted to be a star; it is a portion that can understand the part of you that wanted to conquer, and is afraid to conquer (WL); it is a portion that can understand the guilt you (RC) feel for no reason; it is a portion that can understand the aspirations that you (LD) were unable to fulfill... and if you had fulfilled them, you would not be looking into the subjects that you are looking into now. You would not feel the need to look for answers. It is a part that can understand why you (VM) have so related to this man; it is a part that can understand why the five, and seven, and eight-year-old girl that you were has related to this man, and not independently gone on. It is the part that can understand why you let your aspirations go (TM)."
