If you are dark, make sure you go pitch black

He who is not afraid of death is afraid of nothing at all.
And all these negative energies will become his strength.

There are no cracks in a man who fears nothing.

And from that day on, he does not smile any more

Smile is bad - not serious, very frivolous.

Live like you have a point to prove

I suppose that is one way to live.

No need to explain

No need to explain at all.

Either understand or not - explanation pointless and not required.
