I am asked if I have powered electrical devices or lit light bulbs

Qigong has a bidirectional intention. So qigong master Yan Xin states how, in the book link I gave, a car he was in then had the battery go dead. So then he decided to transfer the electricity from a nearby powerline to restart the car. But he transferred too much electricity so the battery started smoking. So then he reversed his intention and then the car started.

Qigong master Chunyi Lin shared how he was driving and his tire went flat but instead of pulling over to fix it instead he used his qi to reinflate the wheel and keep driving. Then when he got home in the driveway the tire went flat again.

So I am not sure qigong has the intention to power mechanical devices although it can be used that way. There are healers who use electricity as part of their healing but as qigong master Yan Xin says - he proved that even though the household current went through him and the person he was touching was the ground - they felt not shock. Yan Xin said he is able to change is internal resistance and voltage levels to reduce the charge going into the person.

So I am not sure why a qigong master would want to operate "electrical items" because that is not the intention of qigong. Rather the intention of qigong is for healing energy that is done by the Emptiness or Universe. For example qigong master Chunyi Lin said when he got angry then light bulbs would explode in his house or his lawn mower would start smoking as he was mowing the lawn. But he said now from deeper meditation he doesn't get angry long enough to develop that type of intention.

So in other words the intention in qigong is from the Emptiness itself and the "bidirection" is based on the future/past dynamic. So there can be no personal intention for true power in qigong. If there is a personal intention then it has to be reversed as a bidirectional energy.

Western electrical power devices assume a symmetric form of power - the mathematics is symmetrical power and the Emptiness is actually from asymmetric time. I have had this discussion with Nobel physicist Brian Josephson who practices qigong with a colleague at Cambridge. If you look up how National Institute for Standards and Technology or NIST tests the origin of the Volt, the NIST test relies on the Josephson Junction. He received the Nobel Prize for discovering his Josephson Effect which originates from asymmetric power.

So the Josephson Junction has to convert that asymmetric power to a symmetric system. But now Nobel physicist Josephson realizes that the truth of the universe is based on asymmetric power or complementary opposites - this is also called noncommutative phase in relativistic quantum science. So this is what Eddie Oshins at SAIC realized is the secret of Daoist Neigong alchemy training. It's the basic principle underlying all the internal martial arts and the neidan meditation training.

the qi energy is based on frequency. So the blue light is a symptom that the future has been listened to. We can listen to the Universe while it listens to us - so it is a non-local phase wave from the future that we inherently can't see. This is the crux of philosophy as otherwise science and civilization are based on visual external measurements. In science this is called "time-frequency uncertainty." So visualizing light is the means of stabilizing the Emptiness or samadhi - the light gets brighter and more coherent as it is inherently a biophoton laser that self-amplifies from the 5th dimension (that can not be seen).

So with the chakras then we visualize fire but the ancient Chinese fire system uses pyrolysis as a biogas - meaning there are "three chambers" inherently. So the fire takes in the Qi from below - this is the lower chakra - the perineum. That is your lower magpie Bridge as it is called in alchemy - so it is the alchemical Pump that regulates the bellows. So to store up the energy then the anus sphincter has to be flexed and this is quite strange to do all the time consciously. But after the energy builds up then the perineum is activated directly also.

So the dark black energy (Lead) is life force but when it is sublimated it turns red and then green as the wisdom energy of the liver. That is the wood that is undergoing pyrolysis. So the wood actually burns down into the fire (unlike most stoves where the oxygen source is from above). The biogas as sickness qi is then cleared out of the body by going up and it is then burned off as "composted" or tertiary burn - in the third upper dan tien (creating Silver from the blue mercury). So that is the blue light of the third eye - it is the methane being burned off (metaphorically and also biologically).  So you have red, green and blue light. The yellow light is then the spiritual ego as the intention that is harmonizing the whole process.

So the yellow light keeps getting brighter and just as in relativity quantum science - the Gold light is from absorbing the blue light from the future.  So the spiritual ego is based on light that we can see but the virtual photons can not be seen as they are guided by the virtual phonons that are non-local - and then matter is created from the virtual photons. The virtual phonons are inherently the 5th dimension that are instantly in two places at the same time - as eternal motion as the Emptiness.
