Narendra Modi said he has to be more careful of his words now that he is the prime minister.
Addressing millions of students on Teachers' Day, the prime minister, in an answer to a question from a student, said his life has become very busy since he became the prime minister.
"When I was chief minister, I did not have to care much about what I was speaking, but now I have to be careful so that whatever I say does not cause harm to the nation. I remain conscious of what I say," the prime minister said.
He also said that because of his long stint as chief minister of Gujarat, he did not find the role of prime minister very different.
Modi was sworn in the prime minister in May this year.
