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.”

Aside from the bodies identified by Dr. Christine Page, I would like to add another body: the pain -body. The term comes from Eckhart  Tolle. George Sison wrote: “… pain-body describes the accumulation of our painful experiences from the time we were conceived to the present.”

He wrote that it begins to take a life of its own, very much like what we call ego that constantly underscores our imperfections. “This ego, a kind of false self, usurps our so-called true self which is our perfect-self made to the image and likeness of Gd. It then tries with all its might to run our lives.”

My insight is that it is this pain-body , not the devil, that most of the time blinds us to our true self, negating the truth that we are made to the image and likeness of God.

It is this pain -body which prevents us from being Who-We-Really-Are, not any external force.

Dr Page in her book “Frontiers of Health” has a detailed discussion about suppressed emotions registered in the subconscious as pain which affects our choices thus retarding our individual journey into spirituality.

It is important for our spiritual journey that we are aware of our different bodies. Dr Page wrote: “… to unlock the buried emotion and bring the feelings from the ASTRAL BODY through the MENTAL BODY and to resolution on a soul level.”
