- People who have meditated for thousands of hours exhibit a remarkable difference in their brainwaves. Psychologist and author Daniel Goleman says that we can actually see what happens in the heads of those who have achieved “enlightenment.”
- “Perhaps the most remarkable findings in the Olympic-level meditators has to do with what’s called a gamma wave. All of us get gamma for a very short period when we solve a problem we’ve been grappling with, even if it’s something that’s vexed us for months.”
- “We get about half a second of gamma; it’s the strongest wave in the EEG spectrum… What was stunning was that the Olympic-level meditators…their brainwave shows gamma very strong all the time as a lasting trait just no matter what they’re doing,” says Goleman.
DANIEL GOLEMAN: My co-author of the book, Altered Traits, is a neuroscientist, Richard Davidson. He has a lab at the University of Wisconsin. It's a very large lab. He has dedicated scanners. He has about a hundred people working there. He was able to do some remarkable research where he flew Olympic-level meditators who live in Nepal or India, typically, some in France, he flew them over to the lab and put them through a protocol in his brain scanners and did state-of-the-art tests, and the results were just astounding.
He found, for example, that their brain waves are really different. Perhaps the most remarkable finding in the Olympic-level meditators has to do with what's called a gamma wave. All of us get gamma for a very short period when we solve a problem we've been grappling with, even if it's something that's vexed us for months. We get about a half-second of gamma. It's the strongest wave in the EEG spectrum. We get it when we bite into an apple or imagine biting into an apple, and for a brief period, a split second, inputs from taste, sound, smell, vision, all of that come together in that imagined bite into the apple. But that lasts very short period in an ordinary EEG.
What was stunning was that the Olympic-level meditators, these are people who've done up to 62,000 lifetime hours of meditation, their brainwave shows gamma very strong all the time as a lasting trait, just no matter what they're doing. It's not a state effect. It's not during their meditation alone, but it's just their everyday state of mind. We actually have no idea what that means, experientially. Science has never seen it before. We also find that in these Olympic-level meditators, when we ask them, for example, to do a meditation on compassion, their level of gamma jumps 7 to 800% in a few seconds. This has also never been seen by science.
So we have to assume that the special state of consciousness that you see in the highest level meditators is a lot like something described in the classical meditation literature centuries ago, which is that there is a state of being which is not like our ordinary state. Sometimes it's called liberation, enlightenment, awake, whatever the word may be. We suspect there's really no vocabulary that captures what that might be. The people that we've talked to in this Olympic-level group say it's a very spacious sense. You're wide open. You're prepared for whatever may come. We just don't know. But we do know it's quite remarkable.
