In a village there was a small hospital which use to get good number of patients. Once due to an emergency, Doctor has to go to some other village , so before going he thought villagers might come to see him, so better i put a board and go. So he wrote a board saying "AAJ DAWA KHANA BAND HEIN" (in hindi) and left for other village.
. One patient came for his regular check-up , surprised to find doctor was not there , and he read the board
"AAJ DAWA KHANA BAND HEIN" , which means in Hindi "today medicines , no food" , and interpreted meaning that Doctor has advised to take only medicines today no food to be taken and went back.
Second patient came for his regular check-up , surprised to find doctor was not there , and he read the board "AAJ DAWA KHANA BAND HEIN" which means i n Hindi "Today taking medicines is not allowed" , and interpreted meaning that Doctor has advised not to take medicines today and went back.
Third patient came for his regular check-up , surprised to find doctor was not there , and he read the board "AAJ DAWA KHANA BAND HEIN" which means i n Hindi "Today taking medicines and food is not allowed" , and interpreted meaning that Doctor has advised not to take medicines and food today and went back.
Here if we see ( though its a joke) , letters have not changed , nor language has changed , all three patients read same text , in same language , but interpretation was totally different from what Doctor intended to say.
Moral:-
Similar thing will happen when we read shastra , veda's , Upanishads ,Quran or Bible , we have knowledge of language , we might as well understand meaning of words , we have knowledge of interpretation , however our intellect is not that elevated to interpret the same meaning what our Rishi's wanted us to understand.
So we need to sit at lotus feet of able guru and learn them.
