I finally watched Wings of Desire tonight, and besides being a beautifully filmed, poetic and deeply human story, it also has some parallels to some of the things I have written about here recently.
The angels in the movie bear witness to human lives, and also consoles, they provide a gentle and quiet presence. And this reflects the wakeful aspect of Spirit, as pure awareness, and also how (it seems) we experience the soul, or essence, as an alive presence, tangible, quiet, supporting, nourishing.
At the same time, there is nothing more (some of) these angels wants than to fully experience an embodied human life, and many of them do as Peter Falk mentions. And we also see one of the main characters choose a human life.
There is a desire for Spirit and soul (essence) to fuse into human life, for all three to be alive as one, in this individual life. For it to awaken to what it is (Spirit), and who it is (individual soul and human), alive, fused, deepening and maturing into and as this human life.
