Rahu aath wala jaldi bahas mein pad jayega, jo bhi ho biwi ko turant manayega.
The one with Rahu in the 8th will quickly get into arguments; whatever happens, he will immediately pacify his wife.
Rahu in the 8th house is a highly volatile placement, ruling sudden events, hidden anger, and explosive energy.
Dr. Sharma explains how this manifests in domestic life. This person has a very short fuse and will jump into arguments ("jaldi bahas mein pad jayega") over the smallest issues. They will yell, debate, and create a massive scene.
However, the 8th house Rahu also creates a deep underlying fear of abandonment. So, the moment the argument is over, they will panic and immediately apologize to their wife ("biwi ko turant manayega"), doing whatever it takes to restore the peace they just destroyed.
