Haha, what great timing! Just a few days ago I was reading, "The Body Keeps the Score" by Bessel van der Kolk and he wrote about the difference between the left and right brain hemisphere.
Left = logical
Right = emotional
The rudimentary connection I made was that the left side represents Mercury (adult) and the right side represents Moon (child).
I think Saturn can totally switch spots with Mercury if someone lives more in their Parent Mind.
I have a Moon-Mercury conjunction in Scorpio, so when I feel anxious or am emotionally overwhelmed, my ability to communicate and think gets impeded. I've been trying to improve this though 😀
Yes, it all makes perfect sense, thank you for digging it up. and of course, Ida is moon half and Pingala is Sun half.
