Spirituality is closely affected by our endocrine system: Lynn Grabhorn wrote in “Beyond the Twelve Steps”:
“The pituitary is about the size of a hazelnut, shaped like a pear with its mouth at the narrow end. When thought comes into the brain, it hits the pituitary which then secretes a hormone that flows through the brain into he pineal gland another member of the endocrine system.”

“The pineal, a tiny pine cone-shaped gland projecting down from the back of the brainstem, is the guy that’s responsible for amplifying the thought frequencies when they’re received so that they can be dispatched throughout the body.”

I wished I knew all these in the 90s when I was in and out of the hospital  too
often.  Then my voice turned funny. It was because of myasthenia gravis but my HMO would not honor the diagnosis. Eventually I was diagnosed to have severe clinical depression.

I think had I been spiritual instead of being religious as early as the 90s I would not have sank into depression.

One doctor casually said my problem was due to hormonal imbalance but the rest of the medical team over ruled her.

Lynn Grabhorn could have  done me wonders. She wrote:
“Why is all this important [the endocrine system]? Well, your pituitary is the door to God. The more you allow unlimited thoughts into your brain the more it opens, the more it opens, the more you know. And here’s the crux of it: whatever you know;
you will become.”
