This teaches another idea, that those who mourn over their dear ones certainly continue to give pain to those who have departed; because from this world, instead of having a better experience and reflecting it to them, they gather pain and offer it to their dead. The wisest thing that one could do for those who have passed is to project the thought of joy and happiness, of love and beauty, of calm and peace. It is in this way that one can help the dead best. One may ask if one can influence a soul that has passed beyond this world to such an extent as to make him exert a special action on the mind of another person on earth. It is a thing possible in theory, but why trouble that spirit? If you are able to influence that spirit, why not influence this person who is on earth?
