In his new biography, Sachin - The Story of the World's Greatest Batsman, Gulu Ezekiel focuses on the both the public and private side of India's most celebrated sportsman.
With his name in the record books and revered the world over, Tendulkar's face is used to promote everything from luxury cars to soft drinks.
But despite his fame, Tendulkar remains an enigma, even to those who worship him like a god.
'Sachin - The Story of the World's Greatest Batsman' is published by Penguin Books and will be on sale in the UK in late June.
Sachin Tendulkar, for all his fame, remains an enigma for many. How do you explain this?
The interesting facet about Sachin's life is that even though he's a public figure in India, he really does keep his private life, well, very private.
And he really has a wall between what he does on the field and what he does off the field. That's why he continues to be an enigma.

How hard was it trying to get a definitive picture of someone like Tendulkar?
It was difficult in the sense that he does put a wall up around himself and his family. But the advantage for me was that I had been following his career since his schooldays.
There is also an enormous amount of published material on him and his life. So in that way there were a lot of sources for writing this book.
How well did you know Sachin before you embarked on writing this book?
I knew him as a journalist. I can't pretend that I knew him as a personal friend. But I certainly knew him as a journalist and I have interviewed him for television. And I guess what is more important is that he knows me.

In an Indian movie, Anupam Khere, tells his on-screen son: 'You are my son, but he [Sachin] is the son of the entire nation.' How does Sachin manage such huge expectations so well and how does he manage to stay humble through it all?
A very important part of Sachin's life is the fact that he leans a lot on his family. His family is very supportive, by which I mean his parents, including his late father, his siblings and now his wife, have a very steadying influence. They help him keep his feet on the ground.

Although it's nearly impossible to get an insight into Sachin's family life, can you tell us how close he is to his family?
Well, as I mentioned just now, he is really extremely close to his family. The family is very supportive of him. I think that you can really call it a traditional Indian family structure.
It's not quite a joint family, but he is in touch with all of his family members, and they are very close to each other and very supportive of each other.
How does Sachin live? Does he live in relative opulence?
Well, up until last year he was living in the same house that he was born and brought up by his family in. After just getting married in '95 he had moved to a flat above his parent's house - which was in a very middle class apartment building in a very middle class suburb of Bombay.
But since last year he and his wife and two kids have moved into a duplex apartment in the really swanky part of town.
He does lead a rather affluent life, but at the same time he does keep in touch with all his all friends and with his former neighbours.

How much has fame changed Tendulkar?
It's difficult to tell really because the fame he gets here is probably more than any Bollywood movie star or politician, or anybody else.
I always feel that while he is a very level-headed and mature guy, it is really impossible to let it affect your life by one percent or two percent.
I would say that considering the enormous amount of attention he gets, he has done a pretty brilliant job.

What effect has the unfortunate death of Mark Mascarenhas had on Sachin?
First, I think it has had a personal effect on Sachin, because they were really very close: he has described him like his elder brother. And he always stressed that more than an agent he was a friend, and very much an advisor and guide to him.
Financially, I don't think the implications have started setting in yet, because Mark's widow has taken over the company. But I think when it becomes time to renew the contract in a few years, there may be some hurdles and problems.

Pound for pound, Lara has recently said that Sachin is the best. However many here in Trinidad believe that Lara has the edge, as unlike Tendulkar, he has produced several match-winning innings?
The way I see it, Sachin has scored 31 one-day centuries and 29 Test centuries, and as far as one-day cricket is concerned most of those centuries have resulted in victory.
As far as the Test centuries go, if India have not won as many matches as they should have, I think that is because the rest of the team needs to contribute more.
As far as Lara is concerned, at least when he was scoring winning centuries and West Indies cricket had not gone into this deep slump, he did certainly have a very good bowling attack to support his batting, which is something the rest of the Indian team has to look into.
Because you really can't expect a man to do any more than Sachin has and his contribution is fantastic really.

Does India's relative lack of success upset Sachin? And do you think he would swap some of his great individual performances for big series wins by the team?
I can't really speak for Sachin himself, but I can certainly see from the comments he's been making over the years that the relative lack of success, abroad at least, is not something that the team is happy about.
And I am sure that as a team member, and I can't stress enough that he is a team person, I do think it does hurt him.

What does Sachin do outside of cricket to relax?
Sachin really likes to spend a lot of time with his family. Outside of cricket, he loves music, both Indian as well as western rock and pop music. He does a spot of cooking, and he loves to drive. He's got quite a few cars as you can imagine.
He's got two Mercedes and he's got a couple of Fiat's latest models which he endorses in India. And he doesn't have a driver, he loves to drive.

Are there any areas of his game where Tendulkar thinks he has weaknesses?
Actually, he was quoted a few years ago as saying that he did not have any weaknesses, which may sound a bit odd. But every now and then, if he is lbw three times in six-innings, then people will say his weakness is lbw.
But technically I don't think he has any particular weakness against any particular type of bowling or any dismissal. But like any batsman, he does have his occasional slumps. But looking at his record I think in many ways he can't be faulted.
Chetan, India
Do you think that Sachin will ever captain India again?
He might, but quite frankly I hope he does not. I don't think he is ready for it right now. There is a possibility that when he captained them twice before, he was not quite ready for it and he was not quite mature enough.
But it is possible that when he crosses thirty next year he will be mature enough, but right now I don't think his skill will increase over the next year. Right now I think Sourav Ganguly is doing a pretty good job.
