Just a quick note:
Over the years I have read a lot on the "neurology" of "religiosity" and of "spiritual experiences." Some philosophers and some theologists often mention, or offer, their observations and their theories regarding a connection between these types of neurological "conditions" and spiritual/religious experiences.
There is definitely a lot written on TLE and associated proclivities for these types of experiences.
Many of us have had direct experiences as our moods change with Bipolar illness, as well.
Food for thought.
