In doing research, I have found major discrepancies among authors as to the specific aspects of:
the KA
the BA
the AKH
and the SAHU- the parts of soul as defined by the Ancient Egyptians.
From what I can gather, the real meaning of the Egyptian concept of the "REN" is the individual vibration of the soul.
This has to do with the Egyptian Kabbalah (KA BA AKH).
The original Kabbalah was Egyptian, and the purpose was meditation upon the different aspects of the soul, both separately and together in combinations.
This is very, very advanced.
The human soul can at will be divided during meditation.
This is what occurs with deliberate astral projection or involuntary "out of the body" experiences.
Just as the soul can be divided, it can be reunited at will.
The soul can be merged with the soul of another person.
The aura can be expended and contracted at will. It can be programmed to attract or repel anything at will.
The aura can be programmed by sheer will, to act upon the aura of another for better or worse.
Each aspect of the soul can be meditated upon separately and empowered.
Each aspect can invoke and hold each of the elements.
This is very advanced and can be dangerous if one does not know what one is doing.
