You are on the right track
@Lifted_by_the_word by comparing Scripture to the Kingdom of God Within (i.e., Human Physiology).
I have done similar research myself but came to a slightly different conclusion.
Mountains in the Bible are definitely representative of a body part; however, we must interpret said Mountains through the lens of *Salvation*.
Ask yourself...
Is it really the Pineal Gland that offers Salvation? Or does Salvation come from the Seed of Abraham?
Galatians 3:16
"Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ."
Another question...
What body part did the Seed of Abraham spring forth from? What body part does any Male Seed come from?
Genesis 38:9 (KJV)
"And Onan knew that the seed should not be his; and it came to pass, when he went in unto his brother’s wife, that he spilled it on the ground, lest that he should give seed to his brother."
Another translation...
Genesis 38:9 (New International Version)
"But Onan knew that the child would not be his; so whenever he slept with his brother’s wife, he spilled his semen on the ground to keep from providing offspring for his brother."
Now solve the Mystery...
Revelation 14:1
"And I looked, and, lo, a Lamb stood on the mount Sion, and with him an hundred forty and four thousand, having his Father’s name written in their foreheads."
If the Lamb represents the 'seed' or semen that is at the 'head' of Mount Zion, what body part do you suppose Mount Zion then represents?
What did Moses climb to retrieve the Seed of God?
Luke 8:11
"Now the parable is this: The seed is the word of God."
Why does the Bible teach that Mount Sinai is somehow making babies with Hagar?
Galatians 4:24 (New International Version)
"These things are being taken figuratively: The women represent two covenants. One covenant is from Mount Sinai and bears children who are to be slaves: This is Hagar."
Could it be that Mount Sinai represents the body part where Abraham's Seed went into Hagar?
Could it also be that Mount Zion represents the body part where Abraham's Seed goes into Sarah?
What does Mount Zion (where the Seed of Abraham flows from) procreate with?
Abraham 'consummates the marriage' to Sarah when she descends on Abraham's 'Mountain'...
Revelation 21:2
"And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband."
Is it not interesting that the Tree of Life inside of the 'Mother of us all' (Sarah) gives 'Fruit' on a
Monthly Period?
Revelation 22:2
"In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations."
Those 'Fruit' are being fertilized by the 'Water of Life' proceeding from the Seed of Abraham (Lamb)...
Revelation 22:1
"And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb."
Do you see it?
The Meat of the Word is euphemism. It describes Salvation from an adult perspective.
