Obelisks generally remind us of ancient Egypt to which I have always felt a connection. Imagine my surprise when I moved to my current address in Bay Ridge, Brooklyn on 9/1/91 - 33 years ago - and discovered I had an obelisk just outside my window in the park across the street.
Years ago my friend George threw a small clear quartz crystal onto the upper ledge. As far as we know it's still there sharing energies.
There are power sources strategically placed above, below, and on planet Earth, that correspond to others across the grids of reality. They range in size, description, functionality, and other unknowns which we do not yet know how to question. Sometimes they are obelisks or pyramids. Other times they are crystals.
