Time to go back to Gulzar. This is one of my favourite lines ever. Featured in one of Gulzar's seminal movies - Aandhi (1975). The film is based on a female politician - Aarti Devi (played by Suchitra Sen) and her relationship with a hotelier - JK (Sanjeev Kumar). In this particular scene, Aarti is listening to JK reciting poetry over the phone. When he has finished reciting it, he asks Aarti - achchee hai naa?
Aarti reaffirms - "Bahut achchee hai"
JK says "Pataa hai...jab tum achchaa kehtii ho ...bahut hee achchaa lagtaa hai"
"पता है ...जब तुम अच्छा कहती हो ...बहुत ही अच्छा लगता है"
The line is pretty straightforward if you look at it. The male protagonist recited a poem, the female protagonist confirms her approval. But then the male protagonist says, that the approval - the praise becomes ten times more powerful and relevant when it comes from the female protagonist. And that is where lies the proverbial usage of this line. We all have our soft spots or hot spots or whatever else it is that HR calls it these days. These are things that motivate us. You could call them our drivers. Sometimes these 'things' that motivate us - these 'drivers' are not abstract but personified as individuals. So we like it when 'so and so' praises us. Whereas the same praise when received from another individual does not have the same impact. We all have people whose approval we cherish. Whose praise is something we look forward to. Or as JK said
"जब तुम अच्छा कहती हो ...तो बहुत ही अच्छा लगता है"
