Help me understand with the meaning of the following sentence

[kiranlegend]

(Those that aren't Indian struggle to fathom exactly what Tendulkar means to so many millions), and it's doubtful whether even those that live here really comprehend just how much a part of the national consciousness he has become.

Could you please explain what does the sentence in parenthesis mean?

Thanks,
Kiran

Those people who are not of Indian origin have great difficulty in understanding what Tendulkar means to so many millions of people.
