How sitting in Zen meditation

Where is the Dantian?

丹田 Dantian
Dantian are the Qi Focus Flow Centers, important focal points for meditative and exercise techniques such as qigong.

張伯端在《金丹四百自序》內有以下一段：

「要知身中一竅，名曰玄牝，此竅者，非心非腎，非口非鼻也，非脾胃也，非穀道也，非膀胱也，非丹田也，非泥丸也，能知此之一竅，則冬
至在此矣，藥物在此矣，火侯亦在此矣，沐浴亦在此矣，結胎亦在此矣，脫體亦在此矣，此竅乃神氣之根，虛無之谷，即在身中求之，不可求
於他也」

The 竅(Qi Focus Flow Centers) of the body is called 玄牝(The root of creation).
The 竅 are not heart, kidney, mouth, nostrils, spleen, stomach, anal, bladder, Dantian, or brain.

You must know this 竅 well. This is both 冬至(The revival of the sun) and 藥物(神 spirit + 氣qi).
火侯(The fire in the body). 沐浴(Microcosmic Orbit), 結胎(cintamani). It means this too.
It is an out-of-body, a hole, and a source of 神(spirit) and 氣(qi).
The depths of non-existent things. You have to get this in your body, but don't get it anywhere else.

《丘祖秘傳大丹直指》:

「六論玄竅: 人以命門為玄，腎堂為牡，此處立基，謬之千里矣。不知玄牝乃天地之根， 在西南昆地，臍後腎前，而又非臍下一寸三分，亦
非兩腎間之空竅。此乃真竅，能得而 知。上通泥丸，下透湧泉。中接心腎，內虛而直。不可形求，不可意取。先天真種實藏於 此，通天地，
通神聖，得則生矣，失則死矣，“真人之息以踵”者此也。此天仙下手處， 舍此而下，酆九幽者也」。

The 命門(Qi Focus Flow Centers) are not front of the kidney and behind the belly button, 1.5cm below the belly button, or an
empty 竅 between the kidneys.
You have to know that this is a real 竅.
The top is connected to the 泥丸(the crown[top] of the head) and the bottom is connected the 湧泉(the sole of one's foot).

Then, where is Dantian? One cannot quite pin down the Dantian, but it exists.
Then,How do I find Dantian? You can find where the heat originates.
Take a good look at the picture below.

You observe the spine on the opposite side of your belly button or slightly below the belly button. That way it is connected to the Dantian.

玄牝 is a term that comes from the Dao De Jing.

Dao De Jing

[第六章]
谷神不死，The valley spirit dies not, aye the same; 
是謂玄牝。The female mystery thus do we name. 
玄牝之門，Its gate, from which at first they issued forth,
是謂天地根。Is called the root from which grew heaven and earth. 
綿綿若存，Long and unbroken does its power remain,
用之不勤 Used gently, and without the touch of pain.

What is God from a Taoist viewpoint?

What is God from a Taoist viewpoint?

It's a high-level[dimensional] thing that I've reached through the Practice of Taoism.
That's why it's hard to understand what I'm talking about.
What I'm talking about goes far beyond Taoism.

You study only about three-dimensional materials about Taoism. But if you go through some steps, you're going to have four-dimensional.
In fact, in three-dimensional, no one would have reached the highest level of the Taoist reference, such as Microcosmic Orbit (小周天) or 大周天.

Taoism teachers around the world don't know or knew all the details but pretended like he knew nothing about these four-dimensional souls or gods.

There are several reasons,
First of all, they do not have the ability to solve the problem.
Second, most Taoism teachers are taken to miscellaneous Gods. This is why they hide.
Third, groups of darkness are very afraid to know the truth. That's why they disturb organized.

There are invisible beings in our universe.
Unseen beings can compress in three ways. The souls of the dead, the souls of the living and the gods.

If the power[功力] is not high, they can be taken over. Fortunately, high-level gods help the Taoists.
I've mastered the skills to deal with this kind of soul through the years of practice.
And No one in the world has ever had this skills.

Because the skills is Darma[Dharma] of 紫府仙人, the founder of Taoism. And if anyone wants to learn, I can teach you the essence of Taoism for free.

You might be saying, "Stop your big talk until you show us some proof."
Then I would reply:Find a gifted shaman with my pictures and writings, So they will tell you about me. And I can to connect remotely demonstrate by remote  one-on-one healing support.
