Using age as an example now, it may seem to you that you are a given age, that within your subjective experience it must be paramount, that regardless of your age you are to some extent closed off from the experience of being any other age. In some simultaneous existences you are very young, however, and in others very old. Some of your physical cells are brand new, so to speak - the regeneration of fresh life is physically within you; in your terms this is true not only until your death but even after it, when your hair and nails can still grow. Identify then with the constantly new energy alive within you in this now of your being (very intently) and realize that on all levels you are biologically and psychologically connected with that greater identity that is your own.
You may take a break.

Your beliefs automatically attract the appropriate emotions. They reinforce themselves through imagination; and at the risk of repeating myself, because this is so important: Imagination and feeling follow your beliefs. It is not the other way around.

The Nature of Personal Reality, Session 621, Page 69

Your reincarnational selves have as many probable lives as you do. Your beliefs and actions in your present alter “their” experiences, as each of them, in their presents, change yours. If you see these reincarnational selves as one entity, then this becomes quite natural. The whole self is changed by all of its comprehensions.

In terms of personality as you understand it, the individual chooses the abilities he or she will have, and the life challenges. In the present then each person has unlimited opportunity to draw upon the entity´s energy, and the understanding and powers of all of its parts. (Long pause.) It goes without saying that any human being possesses the latent ability shown by a great artist or athlete, or statesman or philosopher. Within creaturehood there are wide ranges of abilities; these may be seldom used, but they are there as practical ideals that can be expressed within that system. In the same way, every individual possesses the abilities of its entity in latent form. These too serve as practical ideals, but in a different kind of context, for you have other centuries to play with and many existences instead of one.

You often excel in situations that utterly escape you at a physical level. These accomplishments still operate through the focus of your present, since you are physically aware of but one line of probable events, so the meaning of many dream events escapes you. But in dreams you often do work quite as valid as any performed in the day, and in the dream state you meet and interact with your own reincarnational selves.

If you remembered such a dream, therefore, you might think that it was precognitive, and that the event would become physical. Instead, the whole portent of the dream event would be an educational one, bringing your fear into clear focus.

Session 720 The Unknown Reality, Volume 2

You must watch the pictures that you paint with your imagination for you allow your imagination too full a reign. You form physical materializations of these realities within your own mind. If you imagine dire circumstances, ill health, or desperate loneliness, these will be automatically materialized, for these thoughts themselves bring about the conditions that will give them reality in physical terms. If you would have good health, then you must imagine this as vividly as in fear you imagine the opposite.
The Seth Material, page 161

“The psyche, as it is turned toward physical reality, is a creator of events, and through them it experiences its own reality as through your own speech you hear your voice.”

Session 784, Page 128, The Nature of the Psyche

Hatred does not exist as a basic psychological structure. It is, however, the result of psychological manipulation of fear; and fear is not a basic psychological structure. Survival is a basic psychological structure. Consciousness survival: construction of this basic psychological structure of consciousness survival must be interpreted, or projected or constructed, in terms of physical survival within your physical field. Inadequate perception, manipulation, or construction in the psychological structure of consciousness survival leads to the psychological creation of fear and hatred. The individual then constructs fear and hatred into physical construction, giving fear and hatred definite physical form. The error is in the original inability to perceive the correct inner data, the basic underlying psychological structure of consciousness survival.

To rid yourself of annoying restrictions then my dear friend, you repattern your past from the present. Whatever your circumstances, you use the past as a rich source, looking through it for your successes, restructuring it. When you search it looking for what is wrong, then you become blind to what was right, in those terms, so that the past only mirrors the shortcomings that now face you.

The personality creates its dreams; the dreams are then experienced. The experience is indelibly recorded, and then changes the personality, again, in the same manner that any experience would.

In order to examine the reality of dreams it is necessary to change the focus of the inner self to those directions in which the inner self moves, when the ego does not limit its scope to camouflage reality only.
The Early Sessions, Book 3, Session 94, Page 51

The breath of life, so to speak, is breathed into the ego by the inner self, but from that point on the ego is independent.
