The 4th house is the house of the mother, domestic peace, and the Moon (water). Mars (Mangal) is the planet of fire, aggression, and war.
When Mars sits in the 4th house, it creates a "Manglik" dosha that specifically targets the peace of the home. Fire and water do not mix. The aggressive energy of Mars boils the calm waters of the 4th house, leading to constant arguments, loss of wealth, and a complete lack of domestic tranquility.
Lal Kitab gives a physical *Nishaniya* (sign) for this placement: There will be an active or unused fire source (like a tandoor, angeethi, or large furnace) kept inside the house. This physical object acts as an antenna, constantly pulling the destructive fire energy of Mars into the home.
🪔 The VAYOM Remedy
If you have Mars in the 4th house, remove any unnecessary fire sources (like a tandoor or old angeethi) from your home immediately. Keep your house cool, and never argue with your mother.
