Your own CONSCIOUSNESS transmits the frequencies, sequences and codes that tell the physical how to take form. You, your attention, what you allow you to think, allow yourself to participate in, allow to continually occur in your own physical timeline.
You do not get to "just leave".... your Crystalline LightBody has to EVOLVE, hold light, activate your crystals, Christed Consciousness, so that you can vibrate, literally, your Quantum Cells will vibrate you into different realities FOR YOU....
Yes, that physical reality is YOUR REAL.... your program.... your play..... All yours.... and how you JUMP TIMELINES it totally up to the amount PHOTONIC LIGHT that you hold (Light Quotient).... in every moment... or the amount of physical matter density that you still hold.
