(Minghui.org) After going through the same tribulations and overcoming them, I now have a deeper understanding about what Master said,

“She’s not just fighting with you on the surface yet still nice to you inside, that’s not how it is. She’s really, genuinely angry. That’s because whoever the karma falls on, that’s who feels the pain. It’s definitely that way.” (The Fourth Talk, Zhuan Falun)

When a practitioner is about to dissolve karma, the karma will leave their dimensional field and fall onto their spouse, who will then feel bad and get upset. In fact, she doesn't know that she's just an actor in this “play” to help you improve.

Practitioners need to clearly understand that their spouse’s actions are to help them pass a test. They should thus maintain peace and thank their spouse from the bottom of their heart. Then the karma can be eliminated and turned into virtue, going back to their field. But if a practitioner fails to maintain their character, the karma will return to their field and wait for the next time to come out again to be eliminated.

Master also said,

“If your mind is always that peaceful and compassionate, when problems suddenly come up, you’ll usually have a buffer and room to think it over.” (The Fourth Talk, Zhuan Falun)

This is my limited understanding of passing a xinxing test.
