 Think of your body of consciousness like your home. If you are allowing someone or something to come inside, then it can affect you for good or for ill. When it is for ill, people are often so affected by the energies they let in that they become depressed or go into a state of numbness. This energy coming in can also be called a psychic attack. The best way to protect oneself from psychic attack is to not react but respond. Even if you have negative energies inside and become low, you can always gain confidence and purification through meditation. Even if you have been spiritually paralyzed by a psychic attack or unwanted negative energies, you can always jump back on track. It can be difficult to always respond instead of react because human nature is driven by emotions, especially the negative ones. The ultimate cure to this is practice. The more we practice forgiveness and responding to situations, the more clarity we receive.
