" In fact, we’re not smart and we have bodies—we’re smart because we have bodies.7 The heart has about 40,000 neurons that play a central role in shaping emotion, perception, and decision making. The stomach and intestines complete this network, containing more than 500 million nerve cells, 100 million neurons, 30 different neurotransmitters, and 90 percent of the body’s supply of serotonin (one of the major neurochemicals responsible for mood and well-being). This “second brain,” as scientists have dubbed it, lends some empirical support to the persistent notion of gut instinct. "

" When SEALs sweep a building,” says Rich Davis, “slow is dangerous. We want to move as fast as possible. To do this, there are only two rules. The first is do the exact opposite of what the guy in front of you is doing—so if he looks left, then you look right. The second is trickier: the person who knows what to do next is the leader. We’re entirely nonhierarchical in that way. But in a combat environment, when split seconds make all the difference, there’s no time for second-guessing. When someone steps up to become the new leader, everyone, immediately, automatically, moves with him. It’s the only way we win. "

" So, when we do experience a non-ordinary state that gives us access to something more, we feel it first as something less—and that something missing is us. Or, more specifically, the inner critic we all come with: our inner Woody Allen, that nagging, defeatist, always-on voice in our heads. You’re too fat. Too skinny. Too smart to be working this job. Too scared to do anything about it. A relentless drumbeat that rings in our ears. This was Silva’s monologue too, but he stumbled onto a curious fact—altered states can silence the nag. They act as an off switch. In these states, we’re no longer trapped by our neurotic selves because the prefrontal cortex, the very part of the brain generating that self, is no longer open for business. "
