This song is about how important to concentrate on the moment you encounter every minutes, every seconds. I think we are good at making life more difficult and complicated by overthinking, and always trying to have "the best". But as time doesn't stop, each moment slips through, nothing stays still. When things don't go well like I expect, I give up trying to control it. Because there is no point holding on  a tree when the ground is moving. Give up and let it go, feel the space you are in.  Tool "Lateralus" is a perfect song to spiral out of the world.
