Ekadashi: Benefits of Ekadashi Vrata

                                                                  Q. Stories abound on the origin of the Ekadasi day. Even more stories are told on the benefits and warnings given for breaking this fast. My question is why we break fast on the Dwadasi at a particular time and what might be the 'result' of breaking ones fast after the allotted time has passed, say if you are traveling or something like that or have just simply forgotten to break fast at the appropriate time.
