Modi, who could not attend the prayer meeting in memory of Advani's wife last Sunday, drove down to Advani's Prithviraj Road residence and spent around 25 minutes with the senior BJP leader.
Kamla Advani, who remained out of politics but was often seen with her husband in public during his long political journey, died on April 6 following cardiac arrest. She was suffering from age-related problems for some time.
Modi was recently in West Bengal where he addressed a few poll meetings while campaigning for the BJP in the assembly polls.
