Budhapa tera manda hi nikalega, jab lagan ka ketu ganda hi nikalega.
Your old age will turn out to be bad, when the Ketu in the Ascendant turns out to be dirty/afflicted.
Dr. Sharma delivers a harsh karmic truth for those with an afflicted Ketu in the 1st house (Lagan).
Ketu represents the final stages of life, isolation, and ultimate liberation. If a person with Ketu in the 1st house lives a life of extreme selfishness, stubbornness, and bad character (making their Ketu "ganda" or dirty), the ultimate price is paid at the very end of their life.
Their old age ("budhapa") will be filled with severe isolation, physical suffering, and misery. They will be abandoned by the very people they tried to control. To prevent this, they must fix their character while they are still young.
