Can someone please translate? I guess it is a saying? 

“İnsan bir ecelini,
Bir de;
Kaderini bilmezmiş..
Bilinen tek şey varmış:
"SEVGİ"
Onun da;
Kıymeti bilinmezmiş..”

Man does not know the time when he is fated to die.

He does not know his destiny either.

There is only one thing known: love.

Nevertheless, its value is not known either.
