This book will work a lot with images. I decided to write it that way because it makes it more interesting, and it's also easier to grasp otherwise complex subjects, which would have to be explained in many more, and often complicated, words.
It's important that we grasp what consciousness is or we will not know what we are doing when we are practicing to become multidimensional. People who are evolved enough to realize that there is something called a soul often think that they, the thinking unit, are the soul and consciousness. This, however, is only partially true.
In my writings, I have distinguished between the Oversoul and the soul, and I am not the first person who does that. The Oversoul is sending out smaller fragments of itself, who become their own personalities, complete with their Fire and Avatar (soul and light-body, where the latter is a shape the soul can take - often the same shape as the physical body, or as an orb).
However, you, who sit there and read this book, are not the soul, but only a fragment of your Oversoul, who is a dweller in other, higher dimensions. A good image we can use, I believe, is that the Oversoul, when using you to explore the 3-D universe, simply uses you like your physical body uses its eyes to explore its environment.
The only difference is that your body has only two eyes, which can only explore one environment at a time, while the Oversoul has multiple upon multiple eyes, which can look in different directions - i.e. in different times, different spaces, and into different dimensions.
Therefore, consciousness is so much more than just you, the personality that reads this book. The Oversoul has the ability to send out factions of itself in all possible directions and receive back what it sees in the form of information, which it stores like a library to share with the All That Is - the Goddess.
The Oversoul is immortal and lives forever, while some say that the fragments can be destroyed, just like your physical body can be destroyed, which in that case means that your personality will cease to exist. Others say that this is impossible, so at this point, it's up to the reader's intuition to establish which one is true and which one is not.
If it's true that our personality can be annihilated, it can happen in space wars because it has been suggested that advanced star races, who have chosen technology before spirituality, have developed weapons that can split the Avatar, and without its form, the soul can no longer exist as a single unit.
Seth, who channeled through the late Jane Roberts, mainly back in the 1960s and the 1970s, describes how he perceives the channeling he's doing from his perspective, and it's quite interesting because it helps us understand how even we, as soul fragments, can split ourselves in smaller pieces and experience another type of reality in another dimension. This is exactly what multidimensionality is.
When I contact your reality, therefore, it is as if I were entering one of your
dreams. I can be aware of myself as I dictate this book through Jane Roberts, and
yet also be aware of myself in my own environment - for I send only a portion of
myself here, as you perhaps send out a portion of your consciousness as you write
a letter to a friend, and yet are aware of the room in which you sit. I send out
much more, than you do in a letter, for a portion of my consciousness is now
within the entranced woman as I dictate, but the analogy is close enough.
Jane Roberts: "Seth Speaks", p. 23, op. cit. 96
Once upon a time, mankind was exactly like Seth describes here. The only difference is that we have physical bodies and Seth does not. In that sense, many would say that we have the privilege because we can experience both the physical/material world and the spirit world simultaneously. We are now very close to being able to do that, and the nano-second helped us tremendously to move in that direction.
