Answer:
Movement is what facilitates the development of theme in a poem. Two types of movements promote the advancement of theme. One is movement of the psyche. Just as we relentlessly move onward in a thicket clearing a way for us on our way, incessantly exercising mind by repeating and singing whatever is already written will bring the immediate next, middle or the last lines in the proposed poem. Nature and Universe is such kind, pleasant and fun-loving to extend a bit from their store. Our wits are only an extension of their's. The second type of movement is that of the physic. Early poets and playwrights were great walkers and travellers which added tremendous kinetic energy to their minds, the fantastic results of which we already can see in the great quantity of immortal poems amassed before us.
