The Tale Of The Princess Kaguya touches upon deep, fundamental human truths. The power behind these truths is timeless, and it has transcended cultures and man-made technologies.
The meanings and symbols within the moral of this story are rooted in the idea that the highest material stature that humanity can create for itself is dwarfed by the inherent wonder and beauty of the natural simplicity and complexity of life.
I could write a book about this movie and story, but I think to do so would be an injustice to it, as one simply needs to behold it to understand its radiance and glory. I'll simply say that this movie is nothing less than an absolutely stunning, wonderous masterpiece of artistry, storytelling, cinema, and humanity.
