The Full Moon’s Effect on People
It is
believed that the full moon has the greatest effect on women and people who are emotionally unstable. During this time, it’s important to keep your emotions in check, as the full moon makes people overly excited and impulsive. At the same time, the full moon gives people an extra boost of energy. So, on the night of the full moon and for the next few days, it’s best to be patient, weigh your actions carefully, and channel your energy into something productive.
The New Moon’s Effect on People
During the new moon, people are influenced by a special energetic impulse. This is a good time to make plans and start new projects, as well as to break bad habits and let go of old grudges. The new moon marks a new beginning—so leave the bad in the past and embrace the good.
