Once there was an old, intelligent woman. She dreamt that she had died. In the dream she saw two ornamental gates with arches which looked alike. As she moved towards the gate she heard a bodyless voice say that one of the guard is a liar.

Both the guards looked alike She thought of how to bring out the truth from them and intelligently she framed a question. She asked the first person ‘What would that other guard say if I asked him which is heaven’s gate? She asked him to report because to bring out the truth from them and to know the gate of heaven. Old woman knew that the man she talked was not telling the truth as the truthful man would only report the bar’s exact words and the liar would twist the truthful man’s words.
