I just watched Song of the Sea, and thought it was a beautiful and heartfelt movie. (One of my favorite bands, Kila, made the music, which is how I got interested in it.)
There is always a lot to be said about stories and how they reflect parts and dynamics in each of us.
In this case, the sister represent intuition, a deeper knowing, and nature connection. The brother a more intellectual knowing, which sometimes leads him astray, until he finds his heart. We all have these two, and they sometimes are at odds with each other, and sometimes more closely aligned. The heart is what brings these two together, as it does in the movie.
The own witch takes away pain by turning herself and others into stone. (Going numb.) We all do that too, in areas of ourselves, and sometimes. It can seem scary to feel, and yet that’s how we thaw, and also how we find our heart.
And the movie is also a reminder that we are nature. We may think we are disconnected from nature, or more connected with nature, which is true in a limited sense. And more truly, we are already nature. We are nature having all these feelings, emotions, thoughts, ideas, impulses, lives. Even our culture and civilization and technology is nature. It’s nature temporarily taking these forms. And when we see it, something shifts. (Similar to how the brother shifted in this movie.)
