"Jacob left Beer-sheba and went toward Haran. He came to a certain place and stayed there for the night, because the sun had set. Taking one of the stones of the place, he put it under his head and lay down in that place. And he dreamed that there was a ladder set up on the earth, the top of it reaching to heaven; and the angels of God were ascending and descending on it. And the Lord stood beside him and said, ‘I am the Lord, the God of Abraham your father and the God of Isaac; the land on which you lie I will give to you and to your offspring; and your offspring shall be like the dust of the earth, and you shall spread abroad to the west and to the east and to the north and to the south; and all the families of the earth shall be blessed in you and in your offspring. Know that I am with you and will keep you wherever you go, and will bring you back to this land; for I will not leave you until I have done what I have promised you.’ Then Jacob woke from his sleep and said, ‘Surely the Lord is in this place—and I did not know it!’ And he was afraid, and said, ‘How awesome is this place! This is none other than the house of God, and this is the gate of heaven’" (Genesis 28:10-17).
I wonder if the ladder represents the seven chakras—center at the back/spine and the rungs of the ladder would lead you from earth to heaven by raising your consciousness higher and higher.
This is a wonderful and important image—both for Jacob and for us. Jacob, having manipulated his father Isaac to bestow on him the blessing that by law should have gone to his brother Esau, is fleeing from his brother's wrath. He is forced to leave all the material things—money, authority—that he had been struggling to claim as his own. He is alone in the wilderness, and only now can he 'remember' his true identity as an expression of eternal Spirit. The dream of the ladder shows him creative consciousness (the angels), not only descending to him from Source but also ascending in the other direction—as he contributes his own creative choices to the infinite.
Your insight connecting the ladder to the chakras is, I think, certainly true. There are indications throughout scripture—from the seven days of creation to the seven letters to the seven churches in Revelation—that there are consistently seven stages in our spiritual development while we are here in mortal form. We move consistently upward as we become more and more expressive of our true Spirit nature. It's important to realize that the energy, like the angels, flows in both directions. We don't leave our lower chakras behind; we transform them through the spiritual awareness we receive as we move higher.
