Brainwave entrainment is a method to stimulate the brain into entering a specific state by using a pulsing sound, light, or electromagnetic field. The pulses elicit the brain’s ‘frequency following’ response, encouraging the brainwaves to align to the frequency of a given beat.

Ultimately, all meditation techniques have the same basic objective – to quiet the chatter of the everyday, waking mind and allow us to enter calmer, deeper states of consciousness. While it is normal for us to become emotionally attached to a particular method we have learned, we should not dismiss other methods that may work just as well, or better, for other people. Indeed, we should actually be wary of techniques that proclaim themselves to be superior, for this is one of the hallmarks of a cult.
Why I am Suspicious of ‘Organized Meditation’
Meditation is arguably the most personal, individualized activity in which one can engage. It is, above all else, a process of personal discovery. Your journey should be uniquely yours. With this in mind, I certainly do not mind receiving tips or advice from an experienced meditator who can help me reach my goals. But I become profoundly uncomfortable when an individual or organization purports to offer the one, single way to “know the truth” or the only “path to enlightenment.” I become even more suspicious when attaining this special knowledge will cost me a lot of money!
I am particularly disturbed by a famous group that claims the allegiance of several celebrities, but I’m not talking about Scientology. Without being too explicit, the name of this group is commonly abbreviated by two letters that also refer to trademarks. The ‘A’-list of devotees used to include The Beatles, and now includes Jerry Seinfeld and David Lynch. This is a group that presents itself as a tax-exempt educational organization, but which is in fact a front for the promulgation of a particular strand of Eastern religion, and has been held to be a religion by U.S. courts and foreign governments. In recent years, it has attempted to gain greater respect in the Western world by clothing its doctrines in more scientific garb, touting a uniquely beneficial brainwave pattern as the result of its techniques. Learning those techniques, by the way, will cost you $1,500 (which is actually $1,000 less than it used to be). This organization runs a university in a Midwestern state, and requires all students to disavow other meditation practices in favor of its own method. Its wealthy advocates are using their influence to spread the word in some prominent media channels, including a recent feature in The Huffington Post, which read like naked propaganda, complete with sycophantic comments in tow.
What bothers me the most about this organization, apart from the horror stories of mental, emotional, and physical abuse that have been revealed by former members, is the organization’s crowing about superior brain wave patterns. This is a topic of great interest to me, so I am naturally curious about developments in this field. Specifically, the claim is that their technique results in demonstrably greater Alpha-wave coherence across the prefrontal cortex and the rest of the brain. And this state of consciousness is presented as the solution to all personal problems, ranging from poor health through enhanced performance to the attainment of world peace. With so much on the line, the price of admission is actually a bargain, right?
The Small Matter of Credibility
At one time, this organization claimed that if a given percentage of the population practiced its technique, the city in which they lived would experience less violent crime and greater economic prosperity. (Such notions were easily debunked by looking at the reality on the ground around their Midwestern campus.) They believe the weather tends to be nice at their college graduations because of their collective influence. And, not all that long ago, they thought they could fly (levitate), producing bogus photographs to “document” this achievement by adherents who had reached the “highest levels.”
Now they say their state of consciousness is superior to everyone else’s – surely the ultimate form of snobbery, an ego-driven emotion from which most meditators actually seek to distance themselves. This claim is just as preposterous as the others that came before. The truth is that there are many ways to achieve the relaxed wakefulness of the Alpha state, and most of them cost less than $50 or are completely free. These methods do not involve chanting the names of Hindu gods as a mantra, and do not lead you to believe that your mantra – for which you paid dearly – is unique to you when it has in fact been given to countless others who happen to be your age and gender.
Brainwave entrainment is a method to stimulate the brain into entering a specific state by using a pulsing sound, light, or electromagnetic field. The pulses elicit the brain’s ‘frequency following’ response, encouraging the brainwaves to align to the frequency of a given beat.
This ‘frequency following’ response of brainwave entrainment can be seen in action with those prone to epilepsy. If a strobe flashes at their seizure frequency, the brain will ‘entrain’ to the flashing light, resulting in a seizure.
On the positive side, this same mechanism is commonly used to induce many brainwave states; such as a trance, enhanced focus, relaxation, meditation or sleep induction. The brainwave entrainment effectively pushes the entire brain into a certain state.
Brainwave entrainment works for almost everyone. It is a great way to lead your mind into states that you might usually have difficulty reaching, allowing you to experience what those states feel like.
THE HYPE
There is a lot of marketing hype around brainwave entrainment. It is sold with promises of increasing IQ, promoting weight loss, ‘mind-tripping’, enhancing creativity, concentration, inducing spiritual states and more.
While these claims are not entirely true, they are not altogether false either. In practice, the claims are based on an overly-simplistic view of how the brain and the brainwaves function.
THE RUB
People are very seldom deficient in a certain brainwave type in all areas of their brain. Usually the distribution is much spottier, with an excess in one area and a deficiency in another.
We are all different, especially when it comes to the distribution of our brainwaves. Boosting a certain brainwave state may be beneficial for one person, and emotionally uncomfortable for another. Without knowing each person’s starting position, entrainment can be rather ‘hit and miss’.
If brainwave entrainment leaves you with unwanted side-effects (see below) or discomfort, you’re probably encouraging a range of brainwaves that are already excessive in some area of your brain. The way around this is to get a brain map to see what your brain’s strengths and weaknesses are, and see what (if any) brainwaves could use some encouragement.
