Himalay by Khalid

Verse1
Jodi himalay hoye dukkho ashey
E hridoye she kichhu noe
Shoto aghateo nishsho je aj
Tar abar haranor bhoe

Chorus
Ki bhule ami eto shoyechhi je betha
Ki kore bhulechhi otitero kotha
Janteo parbe na keu ta

Verse2
Proshno koro na keno hridoy
Dukkhero himalay
Proshno koro na bisuvias
E bukey keno jole roe
Behager shure shukh giye dure
Ashe oshuvo barota

chorus

Verse3
Dol bedhe shob dukkho ashe
Mouno Premer shorbonashe
Bhorer shishir shukobe jenei
Topto rod hashe
Behager shure shukh giye dure
Ashe oshuvo barota
