Planetary energies influence the experience of life on Earth. Just like an electrical storm over an island in the Pacific will change how things feel, so too will a cosmic dance in the solar system affect the Earth and its inhabitants.
Frequencies are emanating from these massive particles (planets). There are cycles and rhythms to these emanations. Each planet has their own rhythm and cycle. These rhythms, which have been going on for a very long time, influence the rhythms of the Earth.
The moon affects the tides, the sun affects our sleep and growth of crops. The luminaries (sun and moon) are easiest to understand as their cycles are short. One day, 28+ days, 365 days. The cycles, or waves, of other planets are not as easy to perceive and understand from the human eye.
The average lifespan only makes it through 2 and a half or 3 Saturn cycles. 40 Venus cycles, less than half of a Pluto cycle and about one Uranus cycle.
If you have ever attempted to master a new skill, you may find that often it takes hundreds if not thousands of repetition to attain mastery. In our lifetimes, the planets are the teachers. In many ways, we barely scratch the surface of their impact. Instead, the Earth is a collection of data and influence from the cosmic neighborhood. Earth is a repository of helpful and well crafted lessons as taught by the planets. We, as souls embodied, are made of Earth. Your cells come directly from Earth material. We came here to learn from and experience the solar system through donning and flesh suit. The material lens through which we experience life has been fostered by and crafted by the space weather. We cannot separate ourselves from the Earth and therefore the Solar System. More generally, we also can, in this case, make no clear separation from the greater galaxy and universe itself.
To a degree, perhaps we can see the Universe as a library of information. The milky way galaxy would be a wing of the library. The solar system, the botany section. The planets each being books on different types of plants. The earth is a volume unto itself. Our body is a few words. Our momentary experiences a few letters.
The point here is that the universe is all information stemming from a single source, however non specific. We, as humans, are many times removed, tangential experience of that source. Our soul, through incarnating in this body, seeks to absorb and experience the specific subset of information garnered within this solar system. We are studying the book of Earth, through the literal act of embodying sed Earth.
There is nothing less important about the experience of Earth as compared to the experience of Source or the Universe. Every bit of information, data, and energy is just as viable as the whole itself. Importance is subjective and is based on criteria that could shift in a moment.
