In English
Let us take another example. You take a healthy student who has got good vision and you ask him what are all the colours he sees around him. He will at once describe that he is seeing several colours and distinguish them. On the other hand, if you choose a student who is suffering from jaundice, and if you ask him what are all the colours he sees around him, his reply will be, I see only yellow colour all over. He will further argue that he is seeing only yellow colour. This is something that is a direct experience of eyes and therefore must be true because he is relying on an authority which we call . But we have also to enquire if these situations are going to last permanently or if there will be some changes in them. We find these are only diseases. They are not natural and will not last all the time.
