Dear Student,

in this paragraph the HCV sir wants to tell that their is no state of rest and motion .every motion and rest is a relative thing.if you define a motion first you have to define the observer frame of reference . let suppose the train is moving on earth. and the observer A is on the earth . then he will say the train is moving wrt earth . so earth is the frame of reference of the observer. lets the observer B inside the train will say train is always in rest because his frame of reference is train only . so the motion is the relative thing if their is mi=otion for someone else then it is not necessary that it for some other also . all depends upon the frame of reference.
Regards
