you can go through two books, one is idols by sunil gavaskar, another all round view by imran khan, in which both of them said that mohinder is the best batsman that they have seen, Lilee considered him the toughest batsman to bowl to, and holding said that a fast bowler knows when a batsman is in pain, but with mohinder there was no clue, he would just stand up and continue...malcom said that he was the bravest batsman that he has ever encountered and Gideon Haigh writing in The Age says: "In an era replete with fast bowling and unrestricted in use of the bouncer, he never stopped hooking - despite many incentives to do so. He received a hairline fracture of the skull from Richard Hadlee, was knocked unconscious by Imran Khan, had teeth knocked out by Malcolm Marshall and was hit in the jaw so painfully by Jeff Thomson in Perth that he could eat only ice cream for lunch"
Rob Bagchi writes. for guardian, "Being hit while batting, though, remains the most conventional way to suffer injury in the game and those who withstood West Indies' attack, and Dennis Lillee and Jeff Thomson during the 70s and 80s, deserve most praise. Chief among them was India's happy hooker Mohinder Amarnath, recalled after a long exile in the Lancashire leagues with Lowerhouse and Crompton, who took them on with, initially, only a solar topee to protect himself. Richard Hadlee fractured his skull, Imran Khan knocked him unconscious, Malcolm Marshall dislodged his teeth, Thomson cracked his jaw and Michael Holding sent him to hospital to have stitches put in his head.
Yet he still managed to score three centuries against Pakistan during the 1982-83 series and warmed up for his starring role in India's 1983 World Cup victory by hitting two more and four fifties in a brutal five-Test tour of the Caribbean. At Old Trafford in 1976 Brian Close and John Edrich, as the wonderful new film Fire in Babylon evocatively shows, were subjected to an 80-minute laceration on the Saturday evening by Holding, Andy Roberts and Wayne Daniel, and most batsmen of the era faced similar tribulations. No one, though, prospered through reckless courage and obduracy quite like Amarnath."
