THE PSYCHIC ARC OF NON-EFFECT
If someone tends to be overly negative or criticizing, it is often due to pain that they feel in regard to themselves and their own life. They cannot deal with things within themselves, and so they "project" them outward onto outside recipients in an attempt to "make it about someone else".
To avoid being a willing reipient of such projections, I recommend something I like to call "The Psychic Arc of Non-effect". It is a spiritual technique of perspective.
First, use understanding and compassionate insight to try and perceive and "feel into" why this person is projecting negativity outward onto others. Are they in pain? Do they feel badly about themselves in some way?
If you can see this source cause of the negativity, you can detach from it and understand that it is not about you. This is the psychic Arc: recognition of source of cause, followed by detachment. Perhaps once you perceive the source of their pain you can even offer compassionate assistance in the way of solace or remedy. But that is your choice, and not an aspect of the technique.
If someone is criticizing or negating you, it is really not fundamentally about you. However, even if something that they say "hits home", and you feel that there is some truth in their criticism, you can humbly use that feedback for self improvement and introspection. In a way, although it is uncomfortable, that is a gift from them. Recognition of source, and a humble attitude of self improvement are powerful deterrents to the attraction of future negative projections from others. The recognition can assist you in feeling less effect from their words. The Humility will cause you to avoid being a target for future negative projections.
AXIOM: Negative projections not reacted to, and not effected by, must return to the sender.
When they see, or feel that you are not effected by their negativity, the energy must then go somewhere else. It is a law of physics. Energy cannot be destroyed. Where does it go? It returns back to the sender as an opportunity for them to clear it up in their own life and consciousness.
Thus you have done them a service, although it may not be comfortable or easy in their case. Instead of being hurt by their projection, you have helped them by providing them an opportunity for self improvement and growth.
You can do all of this without ever uttering a word. It is psychic, non-verbal, and quite powerful.
