It took science awhile to catch up to the mystics. The ancient mystics already knew that the physical world is basically an illusion and that all things are connected. Quantum Theory, in particular, helped cement what the mystics already knew.
Science is about quantifying observable things. We learn a lot through that method. But there’s also an inherent wisdom we’re all capable of tapping into. Human consciousness gives us a type of “knowing” that we can’t quantify or even explain.
