I'm not sure why they are there because the repeated lines are at the end. I've re-aligned them:

Didam ke mra didi wo hayran mandy
Didam ke mra didi wo ro gardandi
Man ba rasm adab ama salamat kardam

Yadm bod dil gham zada ay dar tab ra
Yadm bod khuda hafezi aan shab ra
Man ba rasm adab ama salamat kardam

Pish chashman raqiban khrabm karde
Khrabm karde kharabm karde

Dilbare karde wa har bar jawabm karde
Jawabm karde jawabm karde

Baran zad o man ba gham to dast ba dua mandam
Hayran ze ghamat gashtam o dar kar khuda mandam

Ay way ke dar ein qesa dilt eashiq agar mishd
ba to akherin par sa ay ma jor degar mishod

chashmat atashfishan mah shab asman
degar az man gozasht ba degaran yar bman

easm to amad wa dilshora amanm ra bord
fikr shab hai pas az to hama janm ra bord
hama janm ra bord

pish chashman raqiban khabm karde
Khrabm karde kharabm karde

Dilbare karde wa har bar jawabm karde
Jawabm karde jawabm karde
