On a Tiny Blue Grain of Sand

Even this gigantic twirl of light is just a speckle in the entire Universe...

Our address is
A tiny blue grain of sand near
A yellow hot pebble at the middle of
An arm of a huge twirl of light
That is actually a mere speckle
In this gigantic Universe.

We are just like microbes
Hanging onto this blue grain.
We are so insignificantly small
But our mind is just deep enough
To perceive our insignificance
And the bewildering size
Of this Universe.

Isn't it already extremely significant?

Nothing is too big to be
Placed in our mind.
Although it takes some efforts,
We can house even
The entire Universe within us.

We know only as little about
Our inner universe as the outer one.
Since it does not cost much money,
I want to set out for an exploration
Of this deep and vast Universe
Within me.
