Lal Kitab is the master of physical *Nishaniyas* (signs).
Rahu represents dark, roasted, and addictive substances. Tea leaves (especially dark, boiled tea) carry the energy of Rahu. The 3rd, 6th, and 8th houses are considered the "dark" or challenging houses for Rahu.
When Rahu sits in any of these three houses, the person develops a massive, almost uncontrollable addiction to drinking tea ("chaye peene ka shonk"). They cannot start their day, work, or even think properly without multiple cups of strong tea.
The VAYOM Warning: If you have this placement, your excessive tea consumption is physically activating the negative Rahu in your chart, leading to acidity, anxiety, and nerve issues. Cut down your tea intake to calm your Rahu.
