Thanks a lot @ranahussnainali, for your inputs and making the post more valuable.

Right "DUKH DAROO SUKH ROG BHAIYA" at the time when we forget GOD when we are Sukhi and Dukh is daroo when we attach back to source because of Duks (sufferings). But these sufferings shouldn't last very long.

Guru Jee are Dyaloo Kirpaloo and can't see the long sufferings and pain in the world and therefore prayers for diseased and sick come out of my Guru's Great Heart!
