Once upon a time six blind men went to see an elephant. According to the tale, the first man touched the belly of the animal and said, this is like a wall. The second man touched the teeth and said this is like a spear, the third who touched the trunk said this is like a snake, the fourth touched animal's leg and said this is like a tree, the fifth touched the ear and said this is a fan, and when the sixth man touched the elephant's tail, he shouted ‘Ah! It is like a rope’. They argued with each other for a long time as to what an elephant looks like. They were all looking at the elephant using a particular “angle of view”. We do this often in our lives. We look at only one aspect of an object, ignoring the bigger picture and not recognising that we can look at the same thing using different angles of views.
