The practice aligns/harmonize the Chakras in such a way so as to allow for...
Their annihilation as the serpent is lifted in the 'wilderness' and one by one destroyed and certainly up through the ajna, manas, et alia. Maps of cakras differ depending on issues at hand
to transcend the physical? I wonder what that would look like in a math formula?...
That goes to what I said as well.
The math formulas are in there already in the notes and actually rather fundamental to higher mathematics and physics. Russians, Chinese, American, European mathematicians have all this at their disposal if they get it but of course one may need a "jump start" in terms of what you are saying as well.
So at that point, taking the body or not does not matter. The question of transcending the physical is relevant at that level.
A caveat is that drugs won't do it for even if one has such experiences they are tainted by the influence of the drug itself. Look at shamans for example. I've tried their "stuff". The drugs are garbage for this type of work. In the final analysis they do not work and contradict the process itself. Government as in the US have tried them on unsuspecting citizens to increase intelligence many fold
As for mechanization and building apparatus, I am not certain. I put together a few ideas but you know how American scientists are for the most part - they are assh*les and almost always protecting their union cards. That's why they have become so stupid. They may be worse than Atossa. The process is still "spiritual" as you say.
I know the involvement of both Russian and American scientists in parapsychology.
I know the methods rather well and I've done some experiments in those arenas as well. I've been all over the place. Our government are the biggest assh*les and crooked all the way to the top. That's why America may end plenty soon
Thus, humanity remains in a prison. There is no way they are going to travel into space beyond the solar system in their current physical form. The numbers aren't there and should be a reality check.
This a fitting punishment and may be a prelude to the annihilation of the species itself.
I sounded warnings long ago. For now humans go nowhere. No other corners of the Universe want us. We are worse than the maggots in the garbage can in their view. Look at what we do and how we act.
Some noble souls? Maybe. But as both Jesus and Confucius said don't call anyone "good".
Of course I can't put it all out. These human monkeys would miss the point and try to kill with all this.
But, as the Vedas and Tantras tell us - the kundalini - as the serpent in the wilderness will not be raised for them - in fact it will coil over and bite humanity on the ass.
Hope it helps.
