As a consequence of today’s emphasis on developing the intellect, human beings have become aggressive, critical and separate. This is why they are not happy.
In order to be happy they must work to develop another principle within themselves: their soul.
But the soul can only flourish in the fraternal life where, like bees gathered to make honey, everyone works to realize the will of God and his kingdom on earth.
Once they will have understood the ravages caused by exclusively developing the intellect at the expense of other faculties, human beings will decide to emphasize brotherly relations.
Then, they will find happiness.
