It's a kind of gaslighting, to try to make people believe that they are crazy because they don't accept craziness as truth. To hold firm, we must be able to ground ourselves in truth and not be knocked astray by gaslighting pressures. In Tai Chi, students are trained to keep their center rooted (not lose their balance and be knocked over) and to deflect whatever an opponent directs against them, often causing the opponent to fall from his own energy. We need that kind of rootedness.
