When light passes through a medium it
changes its colour according to medium’s colour. A red flower which is being
seen through green glass seems to be black and when it is being seen through
yellow glass it seems to be pink or orange. This fact can be seen not only in
the field of physics but also in the field of human behavior too. Explanations
of different books, poems and moral sayings are always given by people
according to their attitude. Especially religious books are generally
interpreted by people and groups according their prejudice. An indifferent
observation is very difficult.
