There is such a things called a psychic attack. Whether intentional or not, it is best for all of us to learn about it, what
it is and how to protect oneself from it. A psychic attack, put simply, is negative energy that someone sends your way, with the conscious or unconscious intention to inflict harm upon you, your life or your family. Harm can be launched towards your emotional, physical, spiritual or mental state. It is also an assault upon your aura and without your conscious permission, by another person, place, thing or group. If the psychic attack was done intentionally, we may or may not know who it is causing us harm and what their motives are. The first thing to learn though is to identify a psychic attack and to protect yourself against it.
Protecting yourself from psychic attacks is also about protecting yourself from the day-to-day of life that can sometimes draw in negative emotions, thoughts and people. We are like sponges in that way – especially when you live in a big city or on crowded places – unbeknown to you, you might be picking up negative energy that is harming your aura and personal energy.
Knowing how to shield yourself from all these and then cleansing your aura can help you to maintain your energy and keep your mind and body clear.
