The universally constant influences of each planet by chakra are what we have in common.
Each of the body's energetic chakras (Sanskrit for "disc" or "wheel") have a natural planetary ruler. These characteristics are the same for all people.
In your birth chart the planets rule different specific areas of the body starting from the 1st House at the top of the head, down to the 12th House at your feet. There is further variation depending upon where your signs are situated. Aries rules the face, for example, whereas Capricorn rules the knees.
This is how Vedic astrologers use the birth chart to diagnose and treat physical illness.
