Dogs in Heaven
There is a very beautiful story from the Hindu mythology's Mahabharata that provides an insight to the meaning of our existence.
Five brothers who were kings and their wife, the queen (this happened through a misunderstanding of the concept of 'sharing' as expressed by their mother) after a long reign were embarking on their final journey - to heaven. To do so they had to trek up a mountain and along the way they were joined by a dog.
