In my opinion, “time” is one of the misunderstood Seth concepts. In physical, no action is really simultaneous, there is time. There is something resembling time in non-physical too.
These are some relevant quotes (I believe I have already posted them somewhere):
"On your plane no action is really simultaneous and so time instantly enters in ."
—TES1 Session 14 January 8, 1964" While I am not affected by time on your plane I am affected by something resembling time on my plane . Time has no meaning without barriers. To put it another way, time has no meaning without the necessity to counteract against other actions."
—TES1 Session 14 January 8, 1964“The study of time will teach you much about fifth dimension also . Our imaginary wires composed of solidified vitality are fluid, I hope you understand this, even while they are solidified. For solidity is only illusion.”
—TES1 Session 14 January 8, 1964"The motion of the apparently solidified vitality gives the illusion of time . The counteraction involved in this case is counteraction within the core of vitality itself, in much the same manner that we spoke of a closed mental enclosure, multiplying and setting up motion within itself.
The action and counteraction is the time trigger . To you this will be almost unbelievable, but on some other planes motion is simultaneous and time unknown. To me time can be manipulated , used at leisure and examined. To me your time is a vehicle, one of the several vehicles by which I can enter your awareness. It is therefore still a reality of some kind to me . Otherwise I could not utilize it in any manner whatsoever."
