If we look at the ocean, we see only one world yet for each fish in that ocean, there is a separate world. There is the one that they swim in, and the ones that the other fish swim in. Similarly, we cannot know someone else’s world or can they know ours. The dichotomy is that we are all one, yet none of us are the same. In this universe, there are billions and billions of creatures, and billions and billions of worlds. Before judging someone, try imagining swimming around in their world first.
