One theory is that emotions are the proverbial carrot stick from our subconscious (which origins are unknown) to make us donkeys do what it wants.
Another idea would be to see it as a differential between a desired state and where you are.
You can effectively squash this differential by prudently choosing the correct moves.
For example, one may feel frustrated by misunderstandings when talking with family, friends.
Instead of dwelling upon it, you can act away the frustration:
a) work on your way to convey
b) realize your communication is fruitless
With either choice done, the emotion falls away
I will admit some emotions linger, perhaps because the solution is less than ideal, or maybe it isn't immediately obvious.
Many, for example, would mourn their poverty, and rightfully so.
But as the content of this thread unfolds, you can begin to see that which isn't immediately obvious nor contemplated all too often.
Here's a short story (which I believe was shared here) to convey what I mean:
Alexander, after conquering many kingdoms, was returning home. On the
way, he fell ill and it took him to his death bed. With death staring
him in his face, Alexander realized how his conquests, his great army,
his sharp sword and all his wealth were of no use.
"My first desire is that", said Alexander, "My physicians alone must
carry my coffin." After a pause, he continued, "Secondly, I desire
that when my coffin is being carried to the grave, the path leading to
the graveyard be strewn with gold, silver and precious stones which I
have collected in my treasury". The king felt exhausted after saying
this. He took a minute's rest and continued. "My third and last wish is
that both my hands be kept dangling out of my coffin”.
The people who had gathered there wondered at the king's strange
wishes. But no one dared bring the question to their lips. Alexander's
favorite general kissed his hand and pressed them to his heart. "O
king, we assure you that all your wishes will be fulfilled. But tell
us why do you make such strange wishes?" At this Alexander took a deep
breath and said: “I would like the world to know of the three lessons
I have just learnt.
I want my physicians to carry my coffin because people should realize
that no doctor on this earth can really cure anybody. They are
powerless and cannot save a person from the clutches of death. So let
not people take life for granted.
The second wish of strewing gold, silver and other riches on the path
to the graveyard is to tell people that Not even a fraction of gold
will come with me. I spent all my life with the greed for power,
earning riches but cannot take anything with me. Let people realize
that it is a sheer waste of time to chase wealth.
And about my third wish of having my hands dangling out of the coffin,
I wish my people to know that I came empty handed into this world and
empty handed I go out of this world”. With these words, the king
closed his eyes. Soon he let death conquer him and breathed his last.>>186228
Correct. Why care of things you aren't going to do anything about?
Choose and be done with it
