The words ‘do not grieve’ are not meant to prevent the preacher from grieving. It is, in fact, meant to contradict the impression that Truth is helpless. It means that, in spite of unfavourable conditions, the Truth and supporters of the Truth will finally meet with success. When the adversaries of the preacher of Truth contradict him, they think that they are dealing with a human being. They do not understand that this is tantamount to setting themselves up against God Himself and not merely opposing an ordinary mortal. This state of affairs (i.e. the temporary success of the opponents) continues only till the expiry of the period of human trial. As soon this period is over, God will appear and all these opponents will vanish into thin air. There is no foolishness greater than mistaking the temporary respite during the trial period for unconditional and unlimited liberty to indulge in arrogance.
