Dharmakaya

Not sure about neidan specifically, but in his book he goes into internal alchemy via the three dantiens extensively, that's the main basis of his whole system. And he can apparently produce electric type chi etc, so quite powerful / legit. I would highly recommend reading his book The Master Key if you have not yet, super interesting story, highly informative, and well demonstrates a number of effective practices.

I'm late to the party. But I would think of jing, chi, and shen more in the context of energetic development - i.e. lower, middle, and upper dantiens - and the jhanas as mental states alone. And although the jhanas are interesting and attractive, they are also temporary states and do not confer lasting insight. Thus jhana 4 may be an "emptiness-like" experience, but is not a meaningful insight into emptiness. The jhanas themselves do not lead us to enlightenment, they are but an interesting way station along the path.

For general purposes, relaxed / behind the front teeth is probably fine. Remaining relaxed and conscious of your intention towards energy cultivation (in ren mai / du mai or just generally) is probably more important than any specific tongue position.

True, but close enough? Sometimes I think certain esoteric systems need to be taken with a grain of salt. In this case Luang Pu Wat Paknam may have just been making up his own new system based on an idea he had around "the center of the body", etc.

It's probably the same general idea as the Taoist lower dantien, just in a different spiritual system. Similar to how zen Buddhism talks about developing "hara" which seems clearly analogous to the lower dantien. Pretty fascinating really that a variety of traditions have independently developed roughly similar takes on the human energy body, or they're just cross pollinating..

I'm enlightened you know.. I can tell you how I did it or answer questions. PM me if you're interested.

Hey Wells! Why did you want to attain rainbow body?

Why do you want to achieve rainbow body? As far as I understand it, rainbow body is the result not of having good karma, but of having fully purified one's karma such that none remains. And I think logically, the only person who could achieve this would be a Buddha, as anyone short of Buddha-hood still has remaining karma. So really if you want to attain rainbow body, you are going to have to achieve full enlightenment. As such I think it's no surprise you didn't achieve it in two years, or that many westerners have likewise not achieved it. I think Buddhism, as a meditative system, has a lot to offer, but it also contains much dogma and it can be hard to separate the wheat from the chaff. In my view, Buddhism most basically is a system of progressive attainment; we can see this in a diverse array of teachings, from the Theravada 4 path system to the many complex systems of attainment in Tibetan Buddhism, including Mahayana approaches as well as Mahamudra and Dzogchen. However, without access to an approach or teacher that expressly recognizes progressive attainment, it is no surprise most practitioners experience little genuine realization.

Dawei's first link has an awesome explanation of the three dantiens!

The Master Key by Robert Peng is a good one. His qi gong system is based on the three dantien model, and so he goes pretty in depth about awakening and balancing the three dantiens, and their role in our lives. I would highly recommend it!

Sorry, I would have to say no. I have found that energetic attunements tend need to be overcome in a sense. If you do it of your own initiative however, that's on you. I am sure you have the best intentions, but thinking it over I have found I have definite opinions on this subject, which I have tried to explain below.. An analogy is; imagine we are all in individual space ships, floating around in space. If a foreign ship asks for permission to come aboard and I grant permission, I have willingly opened myself up to a deeper level of scrutiny, so any ill effects are 'on me' so to speak. If I do not grant permission, and an intimate probe attempt is made, the consequences are 'on' the invader. At the same time however, we do not live in bubbles. We are constantly interacting with people on a physical and energetic level, which involves offensive and defensive energetic systems. This is natural interaction and helps us to grow. In the space analogy, we are interacting with many different ships, from well known to foreign, at ranges from close to distant. We are constantly keeping an eye on all of them to varying degrees simply in the interest of self-preservation. For an outside ship to take a look at out craft from a respectful distance, even if we do not let them on board is perfectly acceptable. It is a natural occurrence; certainly we ourselves are looking around at our neighboring ships for various reasons. So if someone take a look at your ship from a safe distance simply because they are interested, with the best intentions there is no harm done, even if we have declined for them to come in closer. Also beyond the space analogy, I generally feel like we exist in an energetic balance such that what we receive from the world mirrors what we put out. So any energetic investigation would necessarily reflect upon us in the manner which we undertake it.

Yes! I am aware it may sound unbelievable, but it's true!

I will bite: yes I have. I had a temporary enlightenment experience in high school and meditated extensively in various Buddhist traditions until I gained a permanent return to that state. I am happy to answer any questions!

I am pretty interested in this as well, and I don't think it's actually that radical. The key is epigenitics. The way I understand it, our DNA is being changed all the time, minutely, through environmental interaction. Environment doesn't just mean where we live, but also our internal environment, how stressed we are, how we feel about the world and ourselves and so on. If stress causes DNA changes, spiritual practice, where ideally we are overcoming our innate issues, the opposite of stress, is thus very likely to be encoded as well in our DNA. Basically, I think epigenetics means everything we do effects us on a chemical - cellular level, no matter how minute, so inevitably spiritual practice is going to have an effect and be recorded. The more progress we make, the more change; an enlightened master has probably altered their genetics more than the average person. We can think about it as our genes are what we're born with, and if we overcome issues like anxiety, or jealousy, maybe this gets passed on, at least to an extent. Another interesting aspect about this is that we only pass on the changes we make to our DNA before we have kids. If we think about average age of reproduction, between 18 and 35, the changes we pass on are those that have occurred growing up and in our early adulthood. In some ways, our parents may have a great effect on what sort of altered DNA we will pass on because they are responsible for our environment in many ways for these early years.

Thanks for sharing your experience! I have read a few NDE books, and it is very interesting stuff. I agree with you, based on my own experiences I definitely believe death is not the end of the road.
