A dimension is a state of consciousness and a level of existence depending on the vibratory rate. Our regular level of frequency, energy, and awareness is thought to be the third dimension. At this level you can see, feel, and touch what you experience. When you go higher into fourth-dimension energies and beyond, you start working with places and spaces beyond time and physical limitations. The benefit of working with these higher dimensional energies is to accelerate and manifest more easily what you want in your life.
It’s fun working on manifesting while in these higher vibrational dimensions and I recommend a few guidelines if you decide to explore these dimensions and spaces.
