Teachers' Day is celebrated every year in India on 5 September to observe the birth anniversary of the country's second President and academic philosopher Dr. Sarvepalli Radhakrishnan.

On this day, teachers and students take a break from their regular academic activities and focus on various celebrations to appreciate their tutors. While some of the students take the responsibility of teaching how to honour their instructors, others celebrate this day by giving gifts to their teachers and expressing their gratitude. 

As India celebrates the 127th birth anniversary of Dr. Radhakrishnan on Saturday, 5 September, we bring to you a few notable quotes from Hollywood celebrities such as Lady Gaga, Ben Affleck, Ricky Martin and Vin Diesel.

Nathan Fillion: I kind of fell backwards into acting. I was studying to be a high school teacher. I look now and I understand completely, or actually barely, how much work it is to be a teacher. It's an incredible amount of work.

Ricky Martin: Heroes represent the best of ourselves, respecting that we are human beings. A hero can be anyone from Gandhi to your classroom teacher, anyone who can show courage when faced with a problem. A hero is someone who is willing to help others in his or her best capacity.

Lady Gaga: Every bit of me is devoted to love and art. And I aspire to try to be a teacher to my young fans who feel just like I felt when I was younger. I just felt like a freak. I guess what I'm trying to say is I'm trying to liberate them. I want to free them of their fears and make them feel that they can make their own space in the world.

Ben Affleck: I grew up in a house with a mother who was a teacher and a Freedom Rider - very left-wing Democrats living in a heterogeneous working-class neighbourhood. I picked up a lot of those values there, and I brought them with me when I showed up in Hollywood.

Josh Turner: I've never had the patience of a teacher.

Big Sean: When I graduated from high school, the teacher said I was throwing my life away following music, and the same teacher invited me back to speak at the school. I don't say that to brag, I just want to be an example.

Kristin Bauer van Straten: My acting teacher used to say that people reveal themselves in their opposites.

Matthew McConaughey: A coach, especially at a college level - much more at a college or high school level, than at a pro level - you're more of a teacher than an actual coach.

Vin Diesel: I was raised in the New York City theatre world. My father was a theatre director and an acting teacher, and it was not uncommon for me to have long discussions about the method and what the various different processes were to finding a character and exploring character and realizing that character.

Archie Panjabi: My mother wanted to be a teacher when she was young, and my father didn't approve of it, so she fought very hard to become one. And she did it. So when I said I wanted to become an actress, my mother was very supportive. She always said to me, 'There's no such thing as 'can't.'

Carrie Underwood: The first one I remember singing on stage was 'Somewhere Out There' from 'An American Tail.' I was around 7, and my choir teacher at school asked me if I would sing it. My parents told me that I needed to move around the stage, so for the entire time I just walked back and forth from side to side while I was singing - there's videotape of it.
