Nathan Brine posts a SHEN vid the same day that I also post a Shen vid - we both talk about frequency of the light!

 well this can be changed - we all have the Yuan Qi inside us deep in the heart and we can build on that. And I learned from when I did 8 hour full lotus meditation - I, one time, promised people I'd do 8 hours of full lotus meditation in one day for $20. So I did that probably seven times and I was seeing lots of blue light and the heart qi got real strong. But I mainly used the energy to heal my family even though people donating said they could feel the energy also. And also they would ask me questions and I would send them the answers I got from meditation. So it was a fun experiment but then my family complained I wasn't making enough money - so the fun lasted only so long. haha. thanks

Nathan Brine vid on Shen.

  yes so the Tibetan Book of the Dead is good on this - essentially at death when we go beyond the heart - there is this moment of Yuan Qi and Yuan Shen bright light. But our subconscious spirit from the yang qi - which is also called the Po Soul - it will lack enough energy to merge with the Yuan Qi. So then the Yuan Shen is not maintained as immortality. So then the person becomes a ghost - that wanders in a dream state based on our subconscious beliefs. John Chang describes this a bit. And then this ghost is actually mainly from the Hun Soul which is the yin qi that then leaves the body, The yang qi has substance as cerebrospinal fluid. So with aging the pineal gland decreases in size from lack of yin qi converting into yang qi as circulation of qi internally. 

So that's why it's easier at a younger age - as the heart yang qi goes down as it has been separated and lost out via the hidden subconscious lower body energy. Yeah so a Yogi then is living with the subconscious at "real" time but the trick is then to keep it at the superconscious level. So that is the Yuan Shen as what the Tibetans call the "Clear Light." 

So the Tibetan monks will feel a person's body right after the person dies and so the part of the body that gets cold first means that's the frequency of the spirit that left the body as their Qi for whether they go to heaven or hell. But as Buddhists they realize these are impermanent realms. So even the Golden "immortal" Yang shen is also impernanet and only the formless Yuan Qi as impersonal formless awareness is real aka the light that can not be seen but only listened to. So that's why that Tibetan medical doctor quote is so great: 

The ear collect the spiraling energy from the cosmos, this energy gives life to man, and we see this vitality in the light which shines forth from our eyes. 

Tibetan medical doctor.

 good question. So Poonjaji or H.W.L. Poonja said the only reason he had taken another body was because of unfulfilled passion or desire. So that is the yang qi as subconscious yin shen also called the Po Soul. Yeah so in the Nondualism tradition of Ramana Maharshi (his main student was Poonjaji) then "eternal liberation" is achieved when the spirit or shen or shakti - it goes through the right side of the heart so that it completely "cuts the knot" to the subconscious yang qi (which is the vagus nerve). So after that - for Ramana he said after 15 minutes of being in just formless awareness then he felt this strong shock on the left side of his heart and then his spiritual ego returned as his personal consciousness. So then after that with each thought and breath then his personal spirit "empties out" back to the formless realm of the Yuan Qi and this is called being a "jnani."  

 And then Chunyi also described - he walked around for two hours with his heart stopped. haha. He does not recommend this - but he said after that experience then people said his healing energy was even stronger and he no longer is bothered by lower emotional blockages. So such a person may get mad for a brief moment but that lower emotional energy gets expressed as the Yuan Qi and so turns immediately back into Love energy from beyond death - as eternal unconditional harmonizing energy of the Universe. So this type of person does not reincarnate. But in Buddhism they say there is Rebirth but there is no soul as a personal eternal being. 

So yeah this gets back to the error of Western logic based on symmetric space as eternity, etc. and the disharmony at the foundation of Western civilization. Anyway - so that's why some yoga traditions teach to NEVER use any "powers" or Siddhis since that's the personal spiritual ego. Whereas the Shakti is supposedly just the Yuan Qi energy as the Yuan Shen - and so if another person is "ready" to receive the "grace" of the Shakti - then they are at the same resonance level with the teacher - and that transfer as resonance occurs. So when the qigong master is healing ghosts then he's sending them back into the bright light of the Yuan Shen that clears out the lower frequency blockages of the ghost. 

So the yin qi is guided by or is based on the frequency of the light as a carrier wave but it's holographic as a laser - and so the light is powered by the Yuan Qi as all of reality. It's just that the yin qi lacks the INTENSITY as amplitude - or concentrated light - to turn the light around of the frequency into the nondualism as noncommutative phase - so that the blue light then absorbs the virtual photon energy from the future. When that happens then this "yin matter" as the Golden Key is activated. So the Yang Shen as new matter or rebirth - is based on the frequency of the previous life.  

This is why a person could have a hidden golden aura from a previous life but it's based on the hidden yin qi - and so they are not consciously aware of it. It's from the yang qi as the subconscious. So this is why the qigong masters say they do not do the healings but actually the Emptiness or Yuan Qi does the healing itself - and they just embody the Emptiness. So that's also called the Cosmic Mother that will Never be Unveiled. 

Or in NDEs someone reported how you can't see God - in the West it's called Creatio Ex Nihilio. Creation from Nothing. But this teaching got covered over by the materialistic idealism of symmetric math, etc.

 I should clarify - Nathan Brine points out the Hun Soul and Po Soul are from before the Yuan Shen is activated. And then the Yuan Shen has the yin shen and yang shen - and both can leave the body out of the eyes - and so you see light externally, etc.

 So Poonjaji said he could look into someone's eyes and then see their past lives. Chunyi also said he could see past lives of people but he rarely tells people unless it would help them with healing. So it's some kind of Yuan Qi Soul activation via a person's Yuan Shen. The Yuan Jing is their Yuan Shen expressed ideally - so when the life force is fullest at start of puberty. So the Yuan Shen can potentially heal a person's body to that level but then the body has to keep emptying out to Yuan Qi to finish the golden immortal yang shen body. haha. So the first physical body is vaporized into Yuan Qi. 

The Nondualism tradition says this is not necessary and once the Yuan Qi is achieved on a permanent level so that the "knot is cut" from the body - then the Jnani just lets their body waste away. The Yuan Qi stays in the body but then when the yang qi of the body wastes away - then at death - the Yuan Qi just remains as Yuan Shen. No golden immortal body - even though while alive a Jnani can manifest a golden yang shen if the Yuan Qi deems it necessary. So other people might encounter the Jnani as another physical body. For example when it was Poonjaji's birthday then his students claims he visited them - something like 6 different households of students had Poonjaji at the same time at their houses - physically there. haha. He does not remember this at all.
