Seth on our thoughts
" Even subjectively you focus upon and indeed manufacture the idea of a relatively stable, relatively permanent conscious self. You stress those ideas and thoughts and attitudes that you recall from "past" experience as your own, completely ignoring those that once were "characteristic" and now are vanished - ignoring the fact also that you cannot hold thought. The thought of a moment before, in your terms, vanishes away.
You try to maintain a constant, relatively permanent physical and subjective self in order to maintain a relatively constant, relatively permanent environment. So you are always in a position of ignoring such change. Those that you refuse to acknowledge are precisely those that would give you a much better understanding of the true nature of reality, individual subjectivity, and the physical environment that seems to surround you.
What happens to a thought when it leaves your conscious mind? It does not simply disappear. You can learn to follow it, but you are usually frightened of turning your attention away from its intense focus in three-dimensional existence. Therefore, it seems that the thought disappears. It seems also that your subjectivity has a mysterious unknown quality about it, and that even your mental life has a sort of insidious dropping-off point, a subjective cliff over which thoughts and memories fall, to disappear into nothingness. Therefore to protect yourself, to protect your subjectivity from drifting, you erect various psychological barriers at what you suppose to be the danger points. Instead, you see, you can follow these thoughts and emotions simply by realizing that your own reality continues in another direction, beside the one with which you mainly identify. For these thoughts and emotions that have left your conscious mind will lead you into other environments.
These subjective openings through which thoughts seem to disappear are in fact like psychic warps, connecting the self that you know with other universes of experience - realities where symbols come to life and thoughts are not denied their potential.
There is communication between these other realities and your own in your dream states, and a constant interaction between both systems. If there is any point where your own consciousness seems to elude you or escape you, or if there is any point where your consciousness seems to end, then these are the points where you have yourselves set up psychological and psychic barriers, and these are precisely those areas that you should explore. Otherwise you feel as if your consciousness is enclosed within your skull, immobile and constricted, and every lost thought or forgotten memory at least symbolically seems like a small death. And such is not the case. "
