brain is becoming more and more relaxed and we are getting more harmonious activity of the brain pattern. A very marvellous color represents the harmony of brain activity.
The colors of stress, the hyperactive colors which were a result of excitement, change one by one and the sky blue color which goes through more changes in the later state of yoga nidra starts to predominate. The light blue color of the sky which represents peace and tranquility begins to appear in the upper parts of the brain. The light blue color becomes deeper and deeper. This shows that the brain is relaxing and a synchronized activity and initiation of a special type of alpha wave, which is the characteristic feature of meditation, starts dominating in the brain.
Special types of electrical waves emanate from the brain known as alpha waves, a sign of tranquility. This starts happening in the fifth or sixth minute of yoga nidra. The tranquility increases to the right of the brain, and it is the right side of the brain that is responsible for meditational activities. That is why this activity of yoga is also a meditation. Now, slowly this blue color moves into the occipital area, into the most important area of the brain which shows how the alpha wave is moving towards synchronization.
Now, this is very important; the synchronization of alpha waves in the brain lobes is actually achieved in the later of yoga nidra. You can begin to see the blue color and colors too. The colors which appear are just the translation of the brain's electrical activity, and in the brain there is a dominance of alpha waves. The brain is relaxed, alert and awake. There is no other technique in the world that keeps the brain alert and at the same time awake and relaxed, all three at the same time. It is only yoga nidra, discovered by Paramahamsa Satyananda, which keeps the mind alert, awake and relaxed, and gives all the benefits of yoga and meditation. So, yoga nidra is a meditation also, while you are relaxing.
Progressively, the slides show how the blue color has spread out over the whole brain; the whole mind has been engulfed by a very synchronized alpha activity which is the characteristic feature of meditation. A little dot of a deep blue color appears, which denotes that the mind has started sleeping. Sometimes during yoga nidra, one can hear somebody snoring. What changes are there, so that we can see why he sleeps and what the benefits are? It is said that one must stay awake
