Dhammapada 1:6

There are those who are aware.
They that are always facing death.
Knowing this they put aside all quarrels.


The first line has a double meaning. I believe it is why there is a pause after aware. It means those that are aware of death, but also those that are enlightened.

On enlightenment:
Once you become aware of the impermanence of all things then the minutia matters not. Spending time worried about pointless things has no real value to it. Instead spend time becoming aware.

On death:
Once death is close the small minutia of life seems so inconsequential. Maybe this is wisdom. When we are young we have an infinite view of life. We are indestructible. As we age we realize how precious life is. The bills, the next door neighbor, the weird hair growing out of your nose, all seem so useless to worry about.
Our time is better spent spending days with our loved ones, or just even watching the birds. This is the real wisdom of this statement. It just doesn't matter. Put aside all the useless fighting and being concerned what the other person is doing and thinking and instead, smell a flower.
