经云：心者君主之官，神明出焉。
又云：心居肺管之下，膈膜之上，附着脊之第五椎，其合脉也，其荣色也，
开窍于耳，又曰开窍于舌。
又云：是经少血多气。
『难经』曰：心重十二两，中有七乳三毛，盛精汁三合，主藏神。
张介宾曰：心象尖圆，形如莲蕊，其中有窍，多寡不同，以导引天真之气，
下无透窍，上通乎舌，共有四系，以通四脏，心外有赤黄脂裹，是为心包络，
心下有膈膜，与脊胁周回相看，遮蔽浊气，使不得上熏心肺，所谓膻中也。

原文说：心是君主之官，神明由此产生。
又说：心位于肺管之下，膈膜之上，附着于脊柱的第五椎骨处，其功能联系脉象，其荣华表现于面色，
开窍于耳，又有人说开窍于舌。
又说：这条经脉（手少阴心经）血少气多。
《难经》说：心脏重十二两，中间有七个乳突和三条毛发，盛放精汁三合，主要功能是藏神。
张介宾说：心脏形状尖圆，外形像莲花的蕊，其中间有孔窍，数量多少不一，用来引导天真的元气，
下方没有透出的孔窍，上方连通舌头，共有四条系带，用来连通其他四脏，心外面有赤黄色的脂肪包裹，这就是心包络，
心下面有膈膜，与脊柱和胁部周围相互对照，遮蔽浊气，使浊气不能向上熏蒸心肺，这就是所谓的膻中。

手少阴心经的经脉，起始于心中，出来归属于心系，向下穿过膈膜联络小肠；它的分支，从心系向上夹行于咽喉，

The classic states: The Heart is the sovereign official, from which Shen (Spirit/Mind) emerges.
It further states: The Heart is located below the pulmonary tube and above the diaphragm, attached to the fifth thoracic vertebra of the spine. Its function connects with the vessels, its luster manifests in the complexion,
and it opens into the ears; it is also said to open into the tongue.
It further states: This meridian (Hand-Shaoyin Heart Meridian) has less blood and more Qi.
The *Nan Jing* (Classic of Difficult Issues) states: The Heart weighs twelve liang, contains seven mammary-like structures and three hairs, holds three he of essence fluid, and primarily functions to store Shen (Spirit).
Zhang Jiebin stated: The Heart is pointed and round in shape, resembling a lotus stamen. It possesses orifices within, varying in number, which guide the Tianzhen (True/Innate) Qi.
There are no perforating orifices at the bottom, but it connects upward to the tongue. There are four ties in total, connecting to the other four Zang organs. Outside the Heart, there is red-yellow fat wrapping it, which is called the Xinbao Luo (Pericardium).
Below the Heart lies the diaphragm, surrounding the spine and hypochondrium, shielding turbid Qi so that it cannot ascend to fumigate the Heart and Lungs. This is what is referred to as Danzhong (Chest Center).

Article:
The Hand-Shaoyin Heart Meridian originates in the Heart, emerges to belong to the Heart system, descends through the diaphragm, and connects with the Small Intestine; its branch ascends from the Heart system along both sides of the pharynx,
connecting to the Eye System; its main trunk returns from the Heart system, ascends into the Lung, descends out of the axilla, follows the posterior medial border of the upper arm,
running posterior to the Hand-Taiyin Lung Meridian and Hand-Jueyin Pericardium Meridian, descends into the elbow, follows the posterior medial border of the forearm, reaches the end of the styloid process of the ulna (sharp bone) at the wrist, enters the posterior medial aspect of the palm,
and emerges from the tip of the little finger (Figure 51).
Article:
The Hand-Shaoyin Meridian originates in the Heart, descends through the diaphragm directly connecting with the Small Intestine; the branch returns from the Lung system, ascending straight to the throat and connecting to the pupil;
the main trunk ascends into the Lung, exits the axilla, passes through Shaohai (HT3) in the posterior elbow region, follows the posterior medial forearm to the palm, and injects into Shaochong (HT9) at the end of the sharp bone.
Note: [1] The Hand-Shaoyin Heart Meridian originates in the Heart, emerges to belong to the Heart system, descends from the Heart system through the diaphragm, and connects with the Small Intestine;
its branch ascends from the Heart system along both sides of the pharynx, connecting to the Eye System; its main trunk
returns from the Heart system, ascends to connect with the Lung, runs posterior to the Hand-Taiyin Lung Meridian and Hand-Jueyin Pericardium Meridian, descends out of the axilla, which is Ji Quan (HT1).
[2] From Ji Quan (HT1), following the posterior medial border of the upper arm, is Qing Ling (HT8).

[5] From Shen Men (HT7), entering the posterior medial aspect of the palm, is Shao Fu (HT8).
[6] From Shao Fu (HT8), following the medial side of the little finger and emerging from its tip, is Shao Chong (HT9), where it terminates,
thereby connecting with the Hand-Taiyang Small Intestine Meridian.
