Natal Chart and Kabbalistic Squares

They affect us depending on the way you use them. Taking the following sentence from the Sun Square page in the Temple of Zeus:

The Kabalistic/Magickal planetary square working empowers the third [solar] chakra, strengthens a weakened/debilitated Sun in one's astrology chart, and helps in the affairs ruled by the house/s with the sign of Leo on the cusp/s and the house containing the Sun.

So, you can use it to empower the third chakra or some aspects ruled by the Sun, but also to empower a debilitated Sun, and the latter case affects us depending on the Sun's position in the houses and aspects formed with other planets.
