From the point of view of physics and physiology, everything that people see through their eyes is nothing more than the reaction of light rays to the cerebral cortex after the nerve impulse formed after the eye stimulates the optic nerve, and the reaction produced in the cerebral cortex.

Xiao Yuan's brainwave connection box is a confined space without any light, under normal circumstances, Xiao Yuan can't see anything even if he opens his eyes, but at this moment he seems to be experiencing a fantasy version of the journey.

I don't know how long after entering the state of selflessness and no-otherness, Xiao Yuan suddenly felt that his eyes lit up, and colorful lights flashed in front of him, making him feel like he was in a time tunnel, this change made him suddenly wake up from the state of selflessness, and his eyes turned into darkness again.

"Humph!" The sharp pain in his head hit again, and he couldn't help but snort.

"What just happened?" Xiao Yuanqiang endured the pain and thought in his heart.

Thinking to no avail, Xiao Yuan thought that the state of selflessness just now could make him ignore the severe headache, and those rays of light also appeared in that state, so he didn't think about it anymore, and continued to cycle his thoughts according to the method just now, wanting to enter the state of selflessness and selflessness again, and at the same time thinking about whether he could see the brilliant light just now.

But because of such a thought in his heart, he couldn't calm down for a while, and his mind wandered on his body for a few weeks, and it was still difficult to enter the previous realm of no other and no self, but because of his eagerness for quick success, he became upset and irritable, as if he had suddenly returned to the original situation, and his headache was like a knife.

"The purer the heart, the simpler the thoughts, the easier it is to enter the realm of no other and no self, this kind of realm is something that many people who practice the inner family mind can meet but cannot seek, you kid and I see that the bottom of the heart is not pure, and the thoughts are not simple, but you can bring the state of no other and no self at your fingertips, and you are not satisfied, and spread it out, which is really the envy of countless martial artists."

Xiao Yuan remembered what the master said when he was in Berkeley, when he asked his master how to enter the realm of no other and no self faster, and at the same time understood why it was difficult for him to enter that realm this time.

"It turns out that I have an obsession in my heart, and this obsession is tantamount to impurities in my heart, which will only cause interference to me." Xiao Yuan quickly understood this, so he adjusted his psychological state again, no longer thinking about whether he could enter the state of no-self, nor thinking about those brilliant lights, just do a good job of pranayama and eliminate all distracting thoughts, and the time to come will naturally come naturally.

After the psychological barrier was crossed, Xiao Yuan quickly calmed down, and after his mind followed the predetermined route for a few weeks, there were fewer and fewer distracting thoughts in his heart, and he slowly sank, forgetting the pain in his head, forgetting himself, and forgetting time, leaving only one thought to start from Shangdantian, thinking about such a cycle over and over again.

The light appeared again, Xiao Yuan was mentally prepared this time, and he didn't even pay attention to these lights, but the more this happened, the clearer these lights became, just like a person looking up at the sky under a clear sky, although he didn't deliberately look at the sun, he couldn't escape the sunlight in the sky, it was there, whether you looked at it or not, you couldn't escape it.

Unable to escape these lights, Xiao Yuan's mind would naturally be partially involved, so a wonderful thing happened.

Inadvertently, Xiao Yuan completed the state of selflessness and dual-use, which is almost an impossible thing to happen under normal circumstances, a person keeps changing to do two different things, and it is inevitable that he will be disturbed by various external factors during the transformation of events, which is also the reason why most people have opposed dual-purpose since ancient times, or think that it is difficult to achieve great things, because to achieve great things, concentration is one of the essential qualities.

The first time Xiao Yuan saw those lights, his attention was diverted, but it directly proved this point by breaking away from the state of no-self and selflessness, but this time it was different, Xiao Yuan paid some attention to those lights, but did not get out of the state of selflessness and no-other, I have to say that this is a thing that can be encountered but not wanted, maybe in the next time, Xiao Yuan may not be able to do this.

The part of the attention that was divided was like a bystander, observing the light, which was a large group of light spots swimming around, all kinds of colors, in the swimming, there were constantly light spots disappearing, but there were also new light points constantly generated, so that all these light points maintained a certain amount of balance in the area that Xiao Yuan could observe.

A thought then came to me: "Where did all this light come from?" ”

However, just as the thought came to him, the light that had been docile suddenly became unstable, and began to swim rapidly in groups, like a school of frightened sardines, and these swims showed a certain regularity.

"What's going on?" Xiao Yuan was taken aback, those points of light moved faster.

"Does it have something to do with my brain activity?" Xiao Yuan suddenly thought of this possibility, from the perspective of biology and physics, all human intellectual activities are actually formed by the connection between the countless neurites of the cerebral cortex through microbial currents, and vision is formed by the optic nerve receiving external light after the biocurrent pulse is transmitted to the cerebral cortex, combined with these two points, Xiao Yuan seems to have found the source of these light spots.

Even as he was thinking about it, the regular fluctuations of those points of light continued.

"It's kind of interesting, if I don't think about anything, will these spots of light revert to the slow swimming state I just saw?."

Xiao Yuan was very amused, and suddenly had such a thought, and decided to give it a try, for this he slowly emptied his consciousness, let himself try not to think about anything, and sure enough, the movement of the light points slowed down, but unless it was a dead person, it was impossible for the brain to be in a state of absolute non-thinking, so although these light points slowed down, the law was not as strong as when he was thinking, but they were still moving, and they didn't really stop.

"Where did these points of light come from?" Xiao Yuan thought about this question again, and had a guess, "Could it be that the current transmitted from the mesh cover on my head strengthens the microcurrent in the cerebral cortex, well, it is very possible!" ”

Just when Xiao Yuan was thinking about this, the movement of those points of light once again showed a strong regularity, and even took him to swim into the distance, creating a feeling of shuttling through time and space tunnel to Xiao Yuan, which was very fantastical.

"This is probably a phenomenon caused by the activity of different areas of the cerebral cortex when I was thinking about it." Xiao Yuan did not get lost in the fantastic and magnificent scene like a time and space tunnel, but continued to calmly think about why this phenomenon occurred, and quickly came to a conclusion.

"If that's the case, can I go to the damaged part of my brain?"

Xiao Yuan suddenly had this idea, the human mind is the freeest, and when he came up with this idea, the neural connections that actually support brain activity had already touched that damaged area, so he saw a scene that surprised him very much.
