According to ecologist Eric Berlow in this 3-minute talk, complex is not necessarily complicated. This sounds to me like the human brain — the most complex thing in the known universe. What that brain does can be complicated — if we are in the grips of habitual thinking or it can be simplicity when we are practicing mindfulness.
He concludes by saying, “For any problem the more you can zoom out and embrace complexity the better chance you have of zooming in on the simple details that matter most.”
This again sounds like it could be the instructions for mindfulness meditation. When we can embrace the complexity of what our brains are doing — the infinite thoughts, the seemingly random chaotic frenzy of the mind we can find in this complexity the simplicity of breathing — “the simple detail that matters most.”
