Mars (Mangal) in the 7th house creates a strong Manglik Dosha. The 7th house is the house of marriage. Mars is the planet of aggression, suspicion, and policing.
When Mars sits here, the husband develops a deeply suspicious and testing nature toward his wife ("patni ko aazmane wala"). He will constantly question her, doubt her loyalty, and create unnecessary arguments just to test her reactions.
Lal Kitab gives a fascinating Vastu *Nishaniya* for this mindset: This person will love planting creepers or vines ("belein") inside the house. Creepers represent Ketu (entanglement and suffocation). By planting them, he physically manifests his desire to entangle and control his wife's freedom.
🪔 The VAYOM Remedy
If you have Mars in the 7th house, uproot all creepers and money plants from your home. Trust your spouse, or your suspicion will destroy your marriage.
