Hi th1996,
An entity attack is different from energetic overload. Energetic overload is when too much purification is happening too fast. An entity attack is when an invisible lower being tries to be bothersome, or even harmful.
If this does happen, usually simply ignoring them is enough and they will go away. They thrive on attention, so if we pay them attention they will often hang around. So, the important thing is to ignore them.
There are severe cases where they can enter someone’s body and try to possess them. If this happens, it is usually because the person has done something in the past that weakens their subtle nervous system, allowing them to enter and try to take hold.
There are a number of things that people can do that weakens their subtle nervous system making them more prone to attack. These include drinking alcohol excessively, taking drugs including psychedelics, sleeping around, sleeping with prostitutes, lying, stealing, cheating on a partner, abusing someone, greed, and having sex with lower entities in return for favours.
Lower entities can certainly put thoughts into people’s heads. These are often referred to as “intrusive thoughts”. They can be thoughts encouraging anger, or blame, or guilt,
or doubt, or instructions to harm others, or harm oneself. They can also be depressing thoughts. Lower entities feed off negative emotions which is why they input these thoughts into people’s minds.
Often it is obvious that a thought is an intrusive thought. It will arise for no obvious reason, or feel out of place, or even feel as if it is coming from “outside” the body.
Spiritual practices, over time, will make people increasingly resilient to these entities. We become spiritually stronger and less effected by them. Eventually we can ignore them whenever they are around, or even command them to leave. We can even help them to move on when we reach the higher stages of the path.
