These parasites as you call them are karmas. 
They are indeed expressions of your ego, and somehow always relate to what you're doing, a subconscious fear, desire, a hate, love, lust. 
Each emotion has been given a voice, what is important is to purify those voices in the name of Jesus Christ and learn to love them all, even the ones that seem like they hate you. They do not hate you, they are you.
You will only endure them in your human body. but I suggest you endure. They teach you lessons about yourself that are vital to your spiritual evolution, as harsh as it may seem it is all rather exciting.

If you want these voices to quiet, then you must quiet your own inner monologue. they are given energy through the same internal system that gives your internal monologue energy. They are essentially the same, but they are thoughts you are having on a subconscious level.

Stop thinking in language, it binds you.
