Red is such an interesting color to correlate with emotion, because it's on both ends of the spectrum. On one end you have happiness, falling in love, infatuation with someone, passion, all that. On the other end, you've got obsession, jealousy, danger, fear, anger and frustration.
One ought never to turn one's back on a threatened danger and try to run away from it. If you do that, you will double the danger. But if you meet it promptly and without flinching, you will reduce the danger by half.
The most successful tempters and thus the most dangerous are the deluded deluders.
The superior man, when resting in safety, does not forget that danger may come. When in a state of security he does not forget the possibility of ruin.
