Creating a Higher Self is the hidden purpose of all major esoteric and religious teachings.
The Higher Self is our Real Self.
It is our Divine Nature.
It is the God within.
It is Immortal.
Our Real Self emerges more definitely the more frequently we experience Presence, and the more deeply we experience Presence. Over the centuries esoteric literature has described the experience of the Higher Self in a myriad of forms: the god Ra in Egypt; the Buddhist state of nirvana; the Garden of Eden and the Sabbath of the Judeo-Christian tradition; the Third Eye of Eastern tradiitons; the state of Zen; the Beloved in Sufi literature; and in more modern times Real I, as opposed to the many 'I's of worldly, mechanical life.
Ouspensky, The Fourth Way: A permanent 'I' does not come all at once. All illusory 'I's disappear little by little and real 'I' gradually grows stronger and stronger, chiefly through self-remembering.
Gurdjieff: What may be called the astral body is obtained by means of fusion, that is, by means of terribly hard inner work and struggle. Man is not born with it. And only very few men acquire an astral body.
Hermes Trismegistus (purported author of the Hermetic Corpus): By God`s mercy there has come to be in me a form which is not fashioned out of matter, and I have passed forth out of myself, and entered into an immortal body.
Liu Yiming (18th c. Taoist master): The spiritual embryo is formless and immaterial; thought it is called embryo, in reality there is no embryo to be seen. The term embryo just describes true awareness becoming solidified, stabilized, not scattering.
Rumi (13th c. Sufi mystic and poet): Presence is the one we call the Beloved.
Upanishads (Hindu text): Bright but hidden, the Self dwells in the heart. He is the source of love, and may be known through love, but not through thought.
Ibn Arabi (13th c. Andalusian Sufi mystic and philosopher ): When the mystery of the oneness of the soul and the Divine is revealed to you, you will understand that you are no other than God. Then you will see all your actions to be his actions and all your attributes to be his attributes and your essence to be his essence.
