Sir, did you plan to become immortal?Sir, generations and generations of Bengali students know you. You were born at Gurap, a very small village in the district of Hooghly. You studied with lots of difficulty, completed your Graduation and used to teach in some well-known and not-so well-known schools of Bengal.
It was perfectly alright. It also speaks of your greatness that you took personal responsibility of your students. You tried your best to make your students genius of Mathematics. You developed problems of Mathematics on your own and forced your students to practise these problems. Some of your illustrious students truly became genius of Mathematics.
But Sir, why did you try to become immortal? Why did you start publishing books containing the problems developed by you? Why did your monkeys have to climb only oily rods-why didn't they find normal rods to reach the top of a house? Why did all those pipes filling water reservoir contain leaks? Couldn't you think of pipes without any leak? Why did the shop-keepers in your book make mistakes, either to weigh or to calculate profit, thus making losses? Couldn't you think of any normal shop-keeper?
Sir, you started publishing your books since 1942. You terrified Bengali students for forty-five long years before your demise. But even thirty years after your death, your innumerable books on various branches of Mathematics have been creating problems for lakhs of Bengali students.
Sir, I was one of such students who used to be terrified by your Mathematics books. But Sir, due to your books, I did not face any problem in solving Maths (Quantitative Aptitude) portion in any competitive examination in which I appeared. Without taking any coaching or guidance, I cleared all those examinations thanks to your books.
Late Keshav Chandra Nag Sir! You truly have become immortal. You will always remain in the minds of crores of Bengali students.
