Generally the rational brain can override the emotional brain, as long as our fears don’t hijack us. (For example, your fear at being flagged down by the police can turn instantly to gratitude when the cop warns you that there’s an accident ahead.) But the moment we feel trapped, enraged, or rejected, we are vulnerable to activating old maps and to follow their directions. Change begins when we learn to "own" our emotional brains. That means learning to observe and tolerate the heartbreaking and gut-wrenching sensations that register misery and humiliation. Only after learning to bear what is going on inside can we start to befriend, rather than obliterate, the emotions that keep our maps fixed and immutable.
