The pineal gland has been said and alluded to as the store house to the spirit.

I would disagree spirit is located only in the brain. Pineal gland is probably some sort of gateway. There is many evidence that consciousness exist beyond brain. (For those who are open minded to see it)

I mean the spirit is in contract in exchange for life: karma, omnipresent, g-d, whatever you like to call it is a real "judge."

I disagree. My opinion is that is one of matrix illusions keeping souls in trap from incarnation to incarnation...
