To go back to Godhead means to reject this material world

One has to return home, back to Godhead, for this is the highest perfection of life. To go back to Godhead means to reject this material world. Although we cannot understand the functions of this material world and whether it is good for us or bad for us, in accordance with the advice of the supreme authority we must reject it and go back home, back to Godhead.
