Rajaram Ramachandran - Man, Know Your Limit

A butterfly sits
On a feathery flower tip.
A sparrow sits
On a slender twig tip.
An eagle sits
On a sturdy treetop.

Each one knows
Its own weight,
A seat it selects,
Knowing its limit,
And up it flies,
To its chosen height.

His own limits,
A man knows not.
Too much he wants,
More than his limit.
It's where he suffers,
Life long, quite a lot.
