Rahu lagan wale ka rang agar saaf hai toh Rahu ke sab gunah maaf hai.
If the complexion of the one with Rahu in the Ascendant is fair/clear, then all the sins of Rahu are forgiven.
Rahu in the 1st house (Lagan) is usually considered a very difficult placement. It can cause confusion, bad habits, and a dark, smoky aura around the person.
However, Lal Kitab has a brilliant physical face-reading technique to check if Rahu is actually harming the person. Dr. Sharma reveals that if a person with Rahu in the 1st house has a naturally very fair, clear, and glowing complexion ("rang agar saaf hai"), it means Rahu is positive!
The clear skin is a physical proof that the "smoke" of Rahu has not corrupted their body or mind. In this case, all the negative effects ("gunah") of Rahu are canceled, and it will only give brilliant intelligence and success.
