Greetings I Bredren,
Selahsie I Love + Guidance.
It is very interesting to hear about the traditions in the I culture, about giving the belongings to the person's family after they pass. If this was important to Greatgrandmama, I think it makes sense if the I great grandmama is not at peace, she would try to get attention from ones in the life realm so the I can help her to be satisfied. The I can ask great grandmama what is it that needs to be done, and maybe once the I do it, the curse and the uneasy spirit of grandmama will be eased.
In the opposite case, Iwombman have a grandfather whose flesh pass a couple years recently. I was able to hold his hand and tell him thank you so much on behalf of our whole family, we love you and we are so thankful for you, and if you are ready to go then we are ready to say goodbye to you. I know that his Irit was at peace when he passed and today, every day, I still feel him and I see the good things that he still does for our family even while he is in another realm. I know that it is true that an ancestor can affect the goings of the family after the person pass flesh. Brother Zion Mtn I am sure the I can find a way to make things right with Great Grandmama and let her bless the family with her peace and joy.
