@Christopher Sartain - I appreciate your study into these topics, and find the research interesting.

When you say about this reincarnated being hypothesis, it is more about the Creator (YHVH) placing its spirit upon specific characters to fulfil its will within this world - here are verses in the Hebrew, where the 'Lord became these characters' (Genesis 39:2 - Joseph, Joshua 6:27 - Joshua, Judges 1:19 - Judah, 1 Samuel 20:13 - Jonathan, 2 Chronicles 17:3 - Jehoshaphat).

Yehoshua was placed as an Angel of the Lord before the people, with the power to forgive sin in Exodus 23:20-23.

Our body has an endocannabinoid system, our brain is regulated by cannabinoids; where a full range of omega oils helps regulate neural firing - so just like vitamin C deficiency causes scurvy, cannabinoid deficiency causes erratic thinking.

Thus rather than "an altered state", it is more an early understanding that certain plants are needed to make us feel balanced, and attuned to the Divine; comparatively our Babylonian society has chosen death & chemicals as a diet, which causes less cognitive thinking, and less connection with the Divine.

The ancient Israelite religion was a sacred ceremony about cannabis, where the Jewish candle holder is in the shape of a cannabis leaf (Exodus 25:31-40).

The prophets, priest were anointed with Holy Cannabis Anointing Oil, and the Messiah is the King of Israel, who would then be anointed to receive Divine instruction.

Schizophrenia isn't really understood very well, as some of the voices in our head are our psyche (Self), some are our own defence mechanisms (ego), and we're all inside God's imagination, so when the brain is properly regulated, we all have the power to hear the Divine - which is what Yoga was about.

Yoga means Connection, and when we have all chakras, & practise all forms of Yoga with cannabis (the Dharmic would use Bhang, Hebrews the Holy Anointing Oil, Zoroastrian Haoma, etc), we can hear the Source of reality (God) communicating with all of us individually.
