When I was about 5 or 6 my mother took me to a screening of the 1940 movie The Bluebird starring Shirley Temple, based on the 1908 play by Maurice Maeterlinck. The story is about a brother & sister, Tyltyl and Mytyl, who are sent out by the fairy Berylune into various magical realms to search for the Bluebird of Happiness. Returning home empty-handed, the children see that the bird has been in a cage in their home the whole time. When Tyltyl gives the bird as a gift to a neighbor's sick child, the bird flies away. The moral is that, ultimately, happiness can be found within oneself.
There are two scenes from this movie which have stayed in my mind all these years later... The first magical realm the children visit is a cottage where their deceased grandparents live. The children have a nice visit with their grandparents, however as they prepare to leave, there is sadness. The grandparents reassure the children that, although they no longer reside in the world of the living, as long as the children hold them in their memories, they will still be awakened to life.
The second scene I loved showed Tyltyl and Mytyl visiting a misty realm where children are waiting to be born. In this realm they are guided by a personification of LIGHT and meet a child who will be born as a new baby into their family.
I hope you find the Bluebird of Happiness in your home and within yourself... always...
