The best defense against this kind of manipulation is to know yourself very well, so you can recognize whether thoughts and feelings are authentically your own or are being “beamed” at you from somewhere, someone else.
A good thing to say is, “I do not consent… No one has my permission to…” and fill in the blank with whatever is happening that you do not want to have happen in your life, for they say that those who harass/harm humans require our permission/consent to harass/harm us. Withdraw your consent ASAP.
It’s a different kind of war… a spiritual war that requires spiritual weapons such as self-knowledge. We under attack on every level: body, mind, heart and soul.
