Kismat (Guru) jab meharbaan hoti hai, kutte (Ketu) ko bhi salaam hoti hai.
*(When destiny (Jupiter) is kind, even the dog (Ketu) is saluted.)*
In Lal Kitab, Jupiter (Guru) represents your ultimate destiny and luck, while Ketu represents a dog, a servant, or someone of lower status.
Dr. Sharma uses a brilliant metaphor to explain the power of a strong Jupiter. When your destiny is shining and Jupiter is blessing you ("kismat meharbaan hoti hai"), your status elevates so much that even your enemies, your critics, and people who previously barked at you like dogs will be forced to bow down and salute you ("kutte ko bhi salaam hoti hai").
When God is with you, the world has no choice but to respect you.
