His second piece, on trolling, was published this week and has resonated with several of Mr Johar's industry colleagues.
The 44-year-old director wrote about the hateful comments that are directed to him on Twitter, several of them ridiculing his sexuality.
"Why is it that every time I put up a pouting picture on Instagram, I'm just called chakka, gay, I'm told "chup kar ch***ye? That's my favourite, by the way. My absolute favourite. Anything I ever say, these three golden words are thrown at me," he said in his column, Karan Affairs.
"I maybe as sad as you, as lonely as you, as messed up as you, but here's what I also know: I'm just a lot nicer than you," Mr Johar told trolls.
On Twitter, several celebrities responded to Karan Johar's piece, including his long-time friend and collaborator Shah Rukh Khan.
