Alongside

Happiness and sadness run parallel to each other.  When one takes a rest, the other one tends to take up the slack. 

Turn on the lights..

''It doesn't matter how long we may have been stuck in a sense of our limitations. If we go into a darkened room and turn on the light, it doesn't matter if the room has been dark for a day, a week, or ten thousand years -- we turn on the light and it is illuminated. Once we control our capacity for love and happiness, the light has been turned on''.
