Fire

There's one thing in this world that is eternal.

Even though everything you see is temporary,

there is one thing in this world that is not only everlasting,

but insatiable.

I know what you philosophers think, it's lust,

and you would not be wrong.

But lust you can not see with material eyes, 

as it has it's place in the polluted mind.

No this you can see, in fact without it, you can't see anything.

It's the mouth of Visnu, or Yajñeśvara.

And if you keep feeding it,

it will never die,

In fact it will increase.

It's always hungry, yet satisfied.

If you keep giving it wood, it will never die.

It will keep on burning until the end of the world.

It's the only thing that you can see and is eternal.
