Measuring Brainwaves🔗

The second procedure we used to look into Swami's brain is known as Quantitative Electroencephalography, or QEEG. QEEG measures electrical patterns in the brain, patterns commonly referred to as brainwaves.

There are four bandwidths of brainwaves, each different in speed, and each associated with a different state of mind. For instance, beta brainwaves are small and fast and linked with an awake, alert state of mind. Alpha brainwaves are slower and larger and are connected to feelings of well-being. Theta waves represent a state of consciousness that is close to sleep, a stage in which there is a sense of calmness and serenity without active thought.

In a day's time, most people will experience all four types of brainwaves. The progression from one bandwidth to another, though, is not so easily in their control.

From Swami's QEEG, though, we can see that he has complete control over his brainwaves. When in deep meditation, his brain smoothly shifted from one state to another, like a talented pianist playing the scales. There was no hesitation and no retreating, just continuous, fluid shifts from one type of brainwave to the next. Because the QEEG represents the five brainwave bandwidths as colors, it was as if we were watching Swami float from color to color within a rainbow!
