Shall your smile change the world, not the world change your smile! - (Adapted from) Sri Sri Ravi Shankar Shankar
There are seconds, they come only five or six at a time, and you suddenly feel the presence of eternal harmony, fully achieved. It is nothing earthly; not that it's heavenly, but man cannot endure it in his earthly state. One must change physically or die. The feeling is clear and indisputable. As if you suddenly sense the whole of nature and suddenly say: yes, this is true... This . . . is not tender heartedness, but simply joy. You don't forgive anything, because there is no longer anything to forgive. You don't really love — oh, what is here is higher than love! What's most frightening is that it's so terribly clear, and there's such joy. If it were longer than five seconds — the soul couldn't endure it and would vanish. In those five seconds I live my life through, and for them I would give my whole life, because it's worth it. To endure ten seconds one would have to change physically . . . .
- Fyodor Dostoyevsky, Demons
This vision seems to express the Zarathustran Übermensch ideal (in this world)!
Many view love as dependency, most often taken as a disharmonious master-slave duality. The Zarathustra character portrays love as a free flowing 'expansion to harmony' uncamouflaged by chains of slavery of mind and heart. By portraying it as a master vs. slave mentality, Nietzsche has been dangerously misinterpreted to be favoring the other side of the master-slave duality equation. But, introspecting into his writing, one realizes that he rather meant having mastery over one's thoughts and emotions as a unified harmony.
Thus, the connection to the above motto. The recommended smile is one that 'appreciates and accepts with a 'yes' saying smile seeking harmony within the whole of the world and therefore doesn't get broken.
How is this motto connected to Zarathustra?
A great motto that seems very simple :) However, I feel that there are a lot of variating aspects around it. Is an outer smile enough? Does it bring about an inner smile too?
Thinking of Robin Williams whose smile definitely changed the world but seemingly failed to help him!
