Our eyes are meant to SEE the sunset. I know that it helps open our third eye.
The sun is a very powerful light to us humans. We NEED the sun. Without it we do not thrive. If you notice that if you are without the sun for an extended amount of time...you'll notice the mood you're in. With the sun, we thrive, happiness shows up, and also it's amazing to have those rays on our skin. The sunset is such a beautiful thing. We NEED to see it. Just like we NEED to see water. Our brains need it.
