Four The Fourth Dimension
As you try to climb the Ladder, expect resistance, someone or something may be coming down. Who's holding up the elevator?
Imagine this fourth symbol to be the two elevator buttons opposing each other, but notice that it resembles the shape of an Hour Glass.

Could our physical universe be like an hourglass, but instead of sand flowing down through the small opening, we have higher energies or entities flowing down into our world? Hmmm? So that's where babies come from!
