Few have commented below that 1 lakh is a paltry amount to donate. But one should remember that it is the intention that is important, not the amount. Besides, Kalam was supposed to have had a frugal life style, which means that he really knew the meaning of hard earned money. Maybe this was because his salary was less. You should also remember that he has always been a government employee, even as a scientist. Therefore it is certainly a big deal that he donated 1 lakh.
