I must not hope.
Hope is the mind-killer
that dilutes your thoughts in possibility.
Hope is the little death that brings total obliteration,
replaces true needs with unreal desires,
makes you lose even when you have won.
I will face my hope.
I will permit it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the hope has gone there will be nothing.
Only truth will remain.
Only I will remain.
