Jab bhi Rahu saat hoga, sasural ki interference se grahasth barbaad hoga.
Whenever Rahu is in the 7th, the domestic life will be ruined by the interference of the in-laws.
The 7th house is the house of marriage and the spouse. Rahu represents the in-laws (Sasural), as well as illusion, politics, and boundary-breaking.
When Rahu sits in the 7th house, Dr. Sharma reveals a very specific and toxic pattern that destroys the marriage. The problem is rarely just between the husband and wife. The real poison comes from the constant, manipulative interference of the in-laws ("sasural ki interference").
The in-laws will constantly meddle in the couple's private affairs, creating misunderstandings and politics that eventually ruin the domestic peace ("grahasth barbaad hoga"). Strict boundaries must be set to save the marriage.
