This teaches us another idea, that those who mourn after their dear ones they certainly continue to give those who have departed pain. 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 most wise thing that one could do for those who have passed is to project the thought of joy and happiness, the thought of love and beauty, the thought of calm and peace. It is in this way that one can help the dead best. God bless you.
