This is one of the most shocking and misunderstood rules of Lal Kitab.
Jupiter (Guru) is the planet of religion and temples. The 7th house is the house of marriage, romance, and Venus (Shukra). Jupiter and Venus are enemies.
If a person has Jupiter in the 7th house, their marriage is already under pressure from the strict, religious energy of Jupiter. If they build a large temple inside their home and actively ring bells ("ghantiyan bajayega"), they are physically amplifying Jupiter's energy in the house of Venus.
The result? The religious energy will completely overpower the romantic energy. The husband and wife will become like brother and sister, or constant arguments will blow their domestic happiness to pieces ("dhajiyan udayega").
🪔 The VAYOM Remedy
If you have Jupiter in the 7th house, do not keep large idols or ring loud bells in your home. Keep your worship silent and internal to protect your marriage.
