According to William Trebing, DC, when you begin a round of physical existence on this Earth, you are born with a certain Resonant Tone which is the actual driving force propelling you into this realm of existence from a more subtle, energetic or astral existence. When considering the Resonant Tone, the process of “rebirth” can be understood not as religion, but as science. Without getting too much into the science of reincarnation, simply understand that you are both an energetic being and a physical being right now, and when you lose this physical body, you will once again be solely an energetic being. Your Resonant Tone has been developing, and evolving to higher vibrations, over thousands of years with concern to continuing physical Earthly lives.
Dr. Trebing says your Resonant Tone is as eternal as your soul, and for all intents and purposes is your soul, which is propelled once again into this physical life-school to expand, learning how to become more and thus evolve to higher states of vibrational existence. The experiences you were born into match the frequencies of your Resonant Tone with the precision of Universal Law. After a rest in the astral (energetic) realm, the densities of your Resonant Tone eventually pull you back into the physical Earth realm, so you may once again evolve. When you “die” from the physical world you are once again born back into the astral realm, each time with more experience and a higher vibrational tone.
After a rest in the astral realm, the densities of our lower vibrational “issues” propel us back into physical existence, so they too may be healed through the experiences of this space/time reality. Physical existence is a perfect school-house for vibrational learning, since although our vibrations of thought and feeling still create our reality, the process of creation moves much slower on the physical Earth than when we are solely in astral existence. Therefore, we have time and a comfort zone enabling us to correct ourselves by making the appropriate changes to what we think and feel. To raise our Resonant Tone and thus evolve, is the only reason for reincarnation. Evolution can also occur in astral existence, but we experience the fruits of our thought far more instantaneously, and thus do not have as much opportunity for correction and reposition. This is why all the sages of this planet have always taught the value and opportunities of a physical Earthly life.
