Beyond The Wise

Have seen the best among the worst,
I've seen the dark before the light
I'm yet to see billionaires,
Without worries
I'm yet to witness love,
Without heartbreaks
Show me world without struggles,
Show me happiness without sorrows,
I can tell truth takes time,
I can tell war brings peace.
Where is the world of ancients before,
the modern?
Where shall we start without ending?
