Instinctively, we protect our physical selves. We don’t let people touch us, push us around, control where we go. But when it comes to the mind, we’re less disciplined. We hand it over willingly to social media, to television, to what other people are doing, thinking, or saying. We sit down to work and the next thing you know, we’re browsing the Internet. We sit down with our families, but within minutes we have our phones out. We sit down peacefully in a park, but instead of looking inward, we’re judging people as they pass by.
