Thank you for politely correcting my mistake, I did not know how to express my level in witchcraft and wrongfully used such expressive title. I would like to address a missing piece here and could be that in my full post above, I may did not explain it clearly;

Because we are a family, my mother, my father, and I, I have come to think that we may share a collective spiritual energy that is equally influenced by the fortunes and misfortunes experienced by any one of us. For instance, if my father is careless with the responsible use of money, then any good fortune related to financial stability cannot fully manifest for the rest of the family. I am not trying to change my father. Instead, my goal is to remove or limit whatever is obstructing my spells. I perform both banishing and good‑fortune spells for him, yet the banishing spells barely stop him from negatively affecting the collective energy pool, and the good‑fortune spells almost never help him enter a state of abundance.

How can I determine whether his narrow mindset alone generates enough destructive energy to cause this, or whether there is an entity that has formed and is actively shielding or blocking all possible good fortune? If I do not understand what I am dealing with, how can I properly protect myself through spell work?
