3. Samael Aun Weor said:
"Whosoever awakens the Consciousness can study all the marvels of the Superior Worlds during the hours of sleep. Whosoever awakens the Consciousness lives in the Superior Worlds as a totally awakened citizen of the Cosmos. One then coexists with the great hierophants of the White Lodge. Whosoever awakens the Consciousness can no longer dream here in this physical plane or in the Internal Worlds. Whosoever awakens the Consciousness stops dreaming. Whosoever awakens the Consciousness becomes a competent investigator of the Superior Worlds. Whosoever awakens Consciousness is an illuminated one. Whosoever awakens the Consciousness can study at the feet of the master. Whosoever awakens the Consciousness can talk familiarly with the Gods who initiated the dawn of creation. Whosoever awakens the Consciousness can remember his innumerable reincarnations. Whosoever awakens the Consciousness can consciously attend his own cosmic initiations. Whosoever awakens the Consciousness can study in the temples of the great White Lodge. Whosoever awakens the Consciousness can know in the Superior Worlds the evolution of his Kundalini." - The Perfect Matrimony
Now, this only emerges gradually, so it emerges slowly within the one who is working seriously.
"...the process of awakening is slow, gradual, natural, without spectacular, sensational, emotional, and barbaric events. When the Consciousness becomes completely awakened, it is not something sensational, or spectacular. It is simply a reality, as natural as a tree that grows slowly, unfolds and develops without sudden leaps or sensational events. Nature is Nature. The Gnostic student in the beginning says, “I am dreaming.” Later he exclaims, “I am in the Astral Body, outside the Physical Body.” Later still, he obtains Samadhi, ecstasy, and enters the Fields of Paradise. In the beginning, the manifestations are sporadic, discontinuous, followed by long periods of unconsciousness. Much later, the Igneous Wings give us continuous uninterrupted awakened Consciousness." - The Perfect Matrimony
