Write what you know

I shall write nothing;
That's what I know best.
Once I was audacious enough
To think
I knew something.
But I know nothing,
And know it well.
Emptiness and nothingness
And all that is unreal
And strange and
Impossible.
These I know:
The vast, empty space
Between each something,
The lack of distinction
Between any thing,
And best of all
The mystical, magical
Mirages, dreams,
Mental landscapes,
Stories, fictions,
And other truths
That those who claim
To know
Reality deny, and call
Nothing.
These nothings are the substance
Of which I shall write.
