I think that without deniel or acceptance of it we may go through some facts :
Suppose a blind man comes to us. He is blind by birth.He requests us to describe about colours. He want to know the differences between green and red. Can we give a satisfactory explanation to him? Another example: A deaf person wants to know the difference between Karnatik song and gazal. How we can give a correct answer to him?
Think whether our language will be helpful in the above matters.If not, how can deny the rishis saying on absolute truth?
