Mafiya,
first of all thanks for reference for this wonderful song.To understand this song, u need to go in to the context, its a desert love story.
"This is a love story of Narwar prince Dhola and Poogal princess Maru. The couple is married in their childhood. Later the father of Dhola, the king Nal died and he forgot the marriage and married the son dhola again to Malwani. Many messages sent form Maru to Dhola but all messages bumped off by Malwani(now second wife of Dhola).
A group of folk singers from Poogal visited the Narwar and Dhola learned about his first wife Maru. Now there comes a lot of hurdles from Malwani and Umar Sumar (who was keen to Maru). He arrived at Poogal and Dhola and Maru were united at last.
In return journey, Maru is bitten by a snake and in sorrow Dhola decides to burn himself as 'male sati'. But he was saved by some yogi and yogini who claimed that they could bring Maru back to life. They played their musical instruments and brought back Maru to life. Umar Sumar again tried to kill Dhola, but however they escaped from there riding back on the wonderful flying camel and the couple along with Malwani lived happily ever after."
Now this song fits in the first para of the story, where Maaru sings (as wind is blowing, giving lovesick maaru pain)"Senraan(saiyan) Ra Baairya re dheemo madhro re baaj,dheemo-2 madhro re baje re bayariya" means - "Oh Wind please be gentle (as maaru is already lovesick and) its blowing from the land of Senraan(dhola) and similarly rest of the song depicts the plight of maaru, wanting for her husband.
Its a heer-ranjha of thar.
