The 7th house is the natural house of Venus (Shukra), representing marriage, partnerships, and daily business.
When Venus sits in its own 7th house, the person's entire destiny and wealth are directly tied to the happiness of their spouse. Lal Kitab gives a beautiful, poetic *Nishaniya* (sign) for this: The jingling of the wife's anklet ("payal").
The sound of the anklet represents a wife who is active, happy, and moving freely around her home. If the husband keeps his wife happy, buys her jewelry, and ensures she is smiling, her positive Venusian energy will act as a magnet, pulling immense wealth and luck into the house. If she cries or sits in depression (the anklets go silent), the husband's destiny will instantly crash.
