It's usually all in the astrological chart and the astrological transits, they shaped our life a certain way. For us to diminish the negative influence they may have, or completely protect from it, we must first learn to read astrology, and identify where the problems are. Once that's done, different workings can be done, such as Magickal Squares/Kabalistic Squares.
However, one may also prevent the negative influence of them by simply meditating, and creating a strong Aura of Protection, as this will prevent most of these unwanted situations. Meditating and creating a strong bioelectric field.
The reason why you would want to create a strong bioelectric field, is because as we know, the way the gravity makes planets move, with that certain frequency of their movement, the waves of energy also impact the earth and all the living beings in it. It's also so powerful that these vibrations have the power to influence our brainwaves and body vibration, as a result impacting our lives.
Therefore, the stronger one is spiritually, the harder it is for these energies to influence one's lives, and the more one meditates the more one gains control over their own life. The stronger our bioelectric field is, the harder will be for these energies to penetrate it and influence ourselves and our lives, as it will dissipate trying to do so. That's why it's also said that the gods are not influenced by astrology.
In conclusion meditate, and build a strong Aura of Protection, gaining control over your own life. Learning astrology will help you as you're advancing, as you'll see if something unpleasant is coming and you will be able to prepare or even use magick to prevent negative events.
