Yaaron ji bhar ke ji le pal
D                Dsus4  A
lagta hai aaj kal
              G
daur apna aayegaa
              A
              
yaaron khud pe ho yakeen
D              Dsus4  A
toh zindagi haseen
              G
tujhe kal bulayegaa
                A

Strumming

Down ... Down Down Up Up Down Up Down

The strumming pattern is a little cagey, modifications appreciated.
