1. Common Sense
Look at all things through the eyes of reason first & foremost. Think of Occam's Razor. IF after thorough examination no rational explanation presents itself, ONLY then look for more implausible possibilities. Example: so much fear surrounds what CC called "the flyers." One explanation is that they are an alien intelligence that survives by feeding on human energy. While that is a possibility (though remote) a far more likely explanation is that we create our own reality through fear of what we don't understand. In this case, are we running from our own "shadows"? Common sense must prevail until such time as it can't. When common sense is abandoned, so is the warrior's ability to function in the tonal.
