Thousands of years ago, weren't we capable of building enormous structures like the pyramids? Weren't we capable of worshiping gods, weaving, making fire, finding lovers and wives, sending written messages? Of course we were. But although we've succeeded in replacing slaves with wage slaves, all the advances we've made have been in the field of science. Human beings are still asking the same questions as their ancestors. In short, they haven't evolved at all.
However happy people say they are, nobody is satisfied: we always have to be with the prettiest woman, buy a bigger house, change cars, desire what we do not have.
We must never stop dreaming. Dreams provide nourishment for the soul, just as a meal does for the body. Many times in our lives we see our dreams shattered and our desires frustrated, but we have to continue dreaming. If we don't, our soul dies, and agape cannot reach it.
