Opposing the elevation of Modi, his one-time protege, as BJP's election campaign committee chief, Advani had resigned from all party posts in June this year, though he later withdrew it.
He had also not attended the party's Parliamentary Board meeting last month which decided to declare Modi as its prime ministerial candidate.
Earlier in the day, both Advani and Modi attended the meeting of Somnath Temple Trust along with trust president Keshubhai Patel.
