My brain is currently sending electro-chemical impulses to my fingers................

Very good.
Now you are saying that everything started from your brain although i point out that they really started from YOU which you confuse for the brain.

"I" am an illusion; an emergent property of my brain. Every single night, my brain has to shut down for cleaning (literally cleaning. The glymphatic system flushes toxins from your brain as you sleep). During most of that time, "I" cease to exist. Only during the relatively brief periods of REM sleep is their brain activity which is interpreted as "me" doing things - this is called "dreaming," and none of the things that "I" do during that time are even real.

All of us, every single human being, gets a daily reminder that, without the brain, the "self" does not exist.

1)Talking, talking but you haven't demonstrated that the matter is able to start any action by itself...

I don't have to. The Universe demonstrates the connection between matter and consciousness on a continual basis. All you need to do is look.

2) Talking talking about the marvels and wonders of the mind as if the mind could start any action by itself or without YOU that decided to start the action.

I don't need to demonstrate anything at all here. I'm merely observing reality, and reporting on what I see. You are the one making an unsupportable claim; it's up to you to demonstrate that this mysterious thing you call "me" and claim exists separate from the brain. The burden of proof is on you.

I see physical reality and emergent properties. I can show them to you.

You claim magical meta-physical woo. Prove it.

3) Talking about consciousness when you haven't got a clue what the consciousness is as demonstrated when you think that the starter of the action is the brain.

You appear to be the one with no clue as to what consciousness is. You're operating on nothing more than objective emotional information. There is no basis to your position whatsoever. You're clinging to an unfalsifiable belief.

All these activities do not explain how a blind person can see things perfectly during the NDE.

They don't. Their brains tell them that they are "seeing." Their brains translate all the available sensory input into images - kind of like the way your brain can "retro-fit" the sound of your alarm clock into a dream. It's an illusion, a hallucination of sorts.

It is essential to note that these instances of "the blind seeing" during NDEs happen only to those individuals who were once sighted, and then lost their sight. This particular illusion has never been observed in an individual who is blind from birth. Why not? Because the brain has no idea what "seeing" is, and therefore cannot create that particular illusion.

Science has never explained how a real guru can send someone into samadhi just by touching his-her head

Of course it has. It's the same phenomenon that Benny Hinn relies on for his 'slain in the spirit' sessions.

You, sir, are plainly ignorant of the science.

"I am ignorant of the science" does not equal "science has not explained." Get thee to a University and learn.

or how someone can insert a knife into his flesh without feeling any pain

Sure it has. Again, your ignorance does not constitute an argument.

and how the hole close as soon as the knife is taken out.

That part is simply parlor-tricks. It's more a matter for James Randi than for Stephen Hawking.
