The Egyptians believed that every human being was composed of physical and spiritual parts or aspects. In addition to the body, each person had a
"šwt" (shadow), a
"ba" (personality or soul), a
"ka" (life-force), and a name. The heart, rather than the brain, was considered the seat of thoughts and emotions.
After death, the spiritual aspects were released from the body and could move at will, but they required the physical remains (or a substitute, such as a statue) as a permanent home.
The ultimate goal of the deceased was to rejoin his "ka" and "ba" and become one of the "blessed dead", living on as an
"akh", or "effective one". For this to happen, the deceased had to be judged worthy in a trial, in which the heart was weighed against a "feather of truth" (seen on top of the head of Maat - the Egyptian goddess who personified the concepts of truth, balance, order, harmony, law, morality, and justice). If deemed worthy, the deceased could continue their existence on earth in spiritual form.

On a separate line of thought, is it possible that every human being existing on earth right now is an "akh" - a wandering soul that has its physical remains (a "Ka" statue) in a different dimension - without even realizing it? Stuck in a stunningly realistic perpetual dream state.
Would it be reasonable to consider psychedelic experiences as a way of taking a brief glimpse at the world we came from - what I'd like to call
"The Beyond"? The DMT entities for example being as real as they sometimes seem, but in a different dimension (the one we came from).
And is dying in this realm just another crossing between this world and the next? How many of those could be stacked? So many questions...but how many of those would leave you sane if answered?
I find Ancient Egypt extremely fascinating to say the least. If any of you has any amazing reads on their traditions and mystical ceremonies, as well as opinions on the above, I'd love if you share them!
Much love, brothers and sisters!
