Astrology is everything and has a very profound meaning. As living beings, we get all our characteristics from the planets and the Sun. For example, our ability to sleep and wake up is both thanks to the solar system. That is, as living beings in the animal kingdom, we can sleep thanks to Neptune and stay awake thanks to Mercury… Mercury makes us brave. We get personal qualities like control and leadership from the Sun, etc. So, everything related to living beings is actually related to astrology.
In astrology, the source of living things is based on the solar system and Pluto system. While the solar system is associated with the animal kingdom, the remaining pluto system is associated with plants. Although Pluto revolves around the Sun, the Pluto system is the second system after the Solar system.
The animal kingdom is related to the solar system in the following way:
Neptune – feet – Pisces
Uranus – ankles – Aquarius
Saturn – knees – Capricorn
Jupiter – thighs, legs – Sagittarius
Mars and (Pluto) – genital organs – Scorpio
Venus – tail – Libra
Mercury – digestive system – Virgo
Sun – heart – Leo
Sun and (Moon) – chest – Cancer
Mercury – arms, hands – Gemini
Venus – neck – Taurus
Mars – head – Aries
Plants are related to the Pluto system, but frankly I don’t know more about it.
