Found out the other day that the rod and staff refers to the pineal gland.
I prefer manly p halls version as this is what is resembling in my life
The pineal gland is the tail of the dragon and has a tiny finger-like protuberance at one end. This gland is called Joseph for it is the father of the God- man. The finger-like protuberance is called the staff of God, sometimes the holy spear. Its shape is like the evaporating vessel of the alchemists. It is a spiritual organ which is later destined to be what it once was, namely, a connecting link between the human and the divine. The vibrating finger on the end of this gland is the rod of Jesse and the scepter of the high priest. Certain exercises as given in the Eastern and the Western Mystery Schools cause this little finger to vibrate, resulting in a buzzing, droning sound in the brain. This is sometimes very distressing, especially when the individual who experiences the phenomenon, in all too many cases, knows nothing about the experience through which he is passing.
