What is the reason for my client’s anger and extreme negativity toward his daughter’s family members? How can we help the situation?

This is old karmic business he is carrying within. There are deep roots that make him distrustful of family and highly resentful because he has been in other lifetimes where he was disregarded and pushed aside, and this was deeply hurtful and eventually compromised his life and brought him to an early demise, in fact. This is what his deep subconscious is most concerned about. Any slight will be interpreted as a sign he is headed for a similar fate in being pushed aside, not honored, and ignored which will be perceived as a grave threat to his well-being because of the prior history here. This is not conscious; it is coming from the deep subconscious within him as great fear and anger as well because he cannot control the situation and feels helpless and exploited. This needs deep karmic repair. The best you can do is to keep the healing going with another round of healing with the Lightworker Healing Protocol to add to prior gains and do prayer work for him to be raised up and become less fearful and oversensitive to the ordinary stresses and strains of family life so people do not have to walk on eggshells, so to speak, to avoid triggering him. His state of mind makes him his own worst enemy as his behavior will naturally tend to alienate those around him, which can feed the problem. There needs to be love and understanding here that he is deeply vulnerable and in need of love all the more as a consequence. That will be the ultimate answer here, to continue receiving love and acceptance despite his rough edges and self-defeating behavior. We understand this is a tall order but is the very best one can do for him. He is a victim of his past. He needs a new present and new future to help him climb out of his dilemma. He will have a hard time doing this on his own.
