It all begins with Mother Earth and Father Moon, soul mates in every way. A full Moon pollinates Earth with cognizant energy during her high tides and in turn Earth bears flesh in the form of humans and other animals, the flesh of humans and other animals clinging to and suckling on Earth and her nature like infants while the cognizant energy of Moon evolves and becomes enlightened, developing into mature fetuses.
Death is birth. Death is leaving the nest and becoming independent. Death is becoming adult. As in life this varies for different people. Some leave home premature while others stay full term, but one truth is universal. Only energy that is good and pure can ascend. That which is compromised and/or corrupt cannot ascend, only be aborted and dragged down by the weight of sin into the swirling vortex of Earth and Moon waste. It's Natural Selection. Only the strong and pure survive and thrive.
Nonetheless, the enlightened pure energy then ascends to the dense milky way community of enlightened pure energy where the energy then hibernates and begins to freeze, forming an earthly or moonly rock and glacial crust. However, this evolutionary hibernation is at will. Some may choose to stay close to Earth and Moon to wait for loved ones before beginning this stage and, in the end, when new soul mate planets set out to find a new sun star to settle and make home, loved ones may stay close and become neighbor planets. It remains that only soul mates complete this process and move on together, although it also stands to reason that those without soul mates in life would then form new unions at this time as well.
We are humans. We are planets. And one day we will become even greater.
But what happens to the other animals? Some may become part of an even greater food chain while others run wild and free throughout the nature of the universe like shooting stars invisible to the eye. All the answers to life's questions can be found in nature. One need only look, listen, and heed.
