Each Zodiac Sign is ruled by specific body parts. This comes from an ancient theory in astrology that the signs of the zodiac parallel the parts of the body. They do so in sign order, from head to toe, from the spring equinox sign of Aries which launches the solar year through to the tail end when we reach the winter sign of Pisces which ends the solar year. While your specific zodiac sign oversees an important part/s of your body, looking at the zodiac as a whole is like looking at your physical being as a complete and integrated organism.
The Zodiac sign Leo is ruled by the Heart and spine. Ancient cultures thought that the heart was far more important than the brain. It's a shame that our modern society no longer holds the heart with as much value. Leo energy indicates the person is a natural born leader and gives it to people "straight from the heart." Being ruled by the spine enhances their bravery. Leos can also be found doing heart centered work such as trades in the arts or healing work. Leo's planet is the sun which gives them their sunny disposition. Tension with the Sun manifests as self-centeredness.
