As spirits go through the incarnations, they learn more and more. Higher Self creates as its own fractal copy from itself (soul personality) for each incarnation. Higher self is always connected to each of these copies although they are independent personalities with free choice. With each incarnation, these personalities learn, grow and become more powerful and more knowledgeable. All this knowledge and power belongs to Higher Self who contains all its fractal copies. As Higher Self grows, at some point of its growth it decides that it is not going to incarnate anymore and it will move on to a higher layer of the spirit world, leaving the 7th density. Before moving on to a higher level, this experienced and much knowing version of the Higher Self takes upon itself a function to serve as a Higher Self guide to all of its previous incarnations. From that point in learning it already knows all its previous and later lives and could guide each incarnation towards learning lessons which might be useful for its future incarnations. Higher self is very wise and loves all its incarnations. Your higher self has the same personality as you, the same character features, and your soul is a fractal copy of its soul. Your higher self contains you and your soul, you are part of your Higher Self.
It is a good idea for your higher self to speak to you in your meditations and to come into your body. You can send your prayers and your gratitude blessings to your Higher Self. You can find the name of your Higher Self by asking them directly or via psychics and channelers. Some people have an open communication line to their higher incarnations such as other dimensional star beings; for example Darryl Anka channels Bashar who is an other dimensional being and who has a body.
