FEARLESS...is much more than just being UNAFRAID...it means that you're WEAK and acknowledge it, it means you're STRONG enough to get back up and MOVE ON. Fearless means you are READY to FACE whatever is headed your way.
Black is associated with power because all vibrational energies of all colors are drawn into one place, ready to be used. Wear black when you feel the need to draw energy to yourself for reviving your strength, energy, and will.
A strong man cannot help a weaker unless the weaker is willing to be helped, and even then the weak man must become strong of himself; he must, by his own efforts, develop the strength which he admires in another. None but himself can alter his condition.
