Daraaz means long,high, exalted
In one of the most classical poems, the poet Iqbal uses this word beautifully.
baag-e-bahisht se mujhe hukm-e-safar diyaa thaa kyon
kaar-e-jahaan daraaz hai ab meraa intazaar kar
Why did you command me to leave paradise
My work here is exalted so now you will have to wait.
