There's no beauty without difference and diversity. Love unconditionally.
The pathos of the human life teaches one that idolatry of the ego is a sham. Only by living in harmonious accord with the entire world can a person distill happiness that flows from cultivating a state of mindfulness.
As a scientist who deals with the deepest secrets of human mind, I know very well that global harmony is something that cannot be truly achieved in a few millennia. Yet it is the most glorious cause worth fighting for as a true sapiens. And I shall keep working for it relentlessly through thousands of generations yet to come.
