Ní-Wán Fū-Rén Dāng-Zhōng Lì
The 'Mud Ball' Madam,
stands ready within its Center.
Jīng Yún Dòng-Fáng Zhōng-Yŏu Fù-Mŭ Mŭ Zé Fū-Rén Yì-Míng Dào Mŭ Ní-Wán Dòng-Fáng Shàng Yǐ Jiĕ-Shì
The Classic says: the Bridal Chamber (a portion of the Brain) has within
its center a Father and Mother.
This Mother [as she is a wife] is therefore called 'Lady' or 'Madam'.
[She is] also known by another name: the 'Dao Mother of the Mud Ball',
located in the Bridal Chamber (a portion of the Brain).
Which is in the upper area, as has already been explained.
Zhǎng-Gŭ Xuán-Xiāng Rǎo Jiāo-Yì
There is the 'Long Valley', the 'Dark Village', and the 'Winding-Around-Suburbs
of the Walled City'.
Zhǎng-Gŭ Bí Yĕ Xuán-Xiāng Shèn Yĕ Jiāo-Yì Wéi Wŭ-Zàng Lìu-Fŭ Yĕ
The 'Long Valley' is the Nose,
the 'Dark Village' is the Kidneys,
and the Winding around of the 'Suburbs of the Walled City' are the Five Viscera
which are the Six Official Residences (of the gods in the body).
Yán Bí-Zhōng Qì Chū-Rù Xià Wéi Shèn Yùn Zhōu Rǎo Zàng Fŭ Jū
Chì-Chéng Cún Xiǎng Nèi Xié Wài Jiāo Gù Wéi Xiàng Yù Yĕ
What is being said is first the area around the Nasal Septum is where
the Qi comes in and goes out. It moves down to the Kidneys. Carried in a
circular pattern, [the Qi] winds round the Storage Area (Zang),
the official residence which is the dwelling-place of
the 'Red-Walled City Boy' who exists by choice within it.
Badness and perversity reside outside the suburbs.
Therefore, because this is how it looks, the analogy is made.
