I'll preface this by saying that some of the images of children are disturbing. Each one is a flash across the screen, though...and the video doesn't dwell on that aspect for long. I did watch to the end (12:36 in length) and it may seem longer because the unfolding story of Earth isn't anything we ever wanted to be true. By the end, you may be going for some tissues, but not in sorrow...in gratitude.
We've been blissfully (relatively speaking) unaware of the nature of the troubles this world has seen, but we do need to understand it in order to counter it effectively. And what do we have to do so?
Our Light! Embracing our innate Divine Nature and the power of our Hearts and intentions is actually all we need to focus on. Yes, we need a certain level of awareness of what we're up against, but it's a practice of Mastery to have that awareness and still maintain a perspective from altitude.
