The relationship between the Heart and the Kidneys in Chinese Medicine is the basis for having a clear sense of purpose and the drive to live out that purpose.
Physiologically, the Heart plays a vital role in sustaining our lives, bringing oxygenated blood throughout the body to nourish its estimated 100 trillion cells. On the other hand, the Kidneys are vital organs that help eliminate waste products from the blood to prevent autointoxication.
In Chinese Medicine these two organ systems have other dynamic and critical functions that are important to understand if we are to cultivate healthy longevity in body, mind and spirit.
The Heart stores the Shen, or Spirit, and the Kidneys store the Zhi, or Willpower.
The Kidneys are also the storage center for the Jing, or Essence.
Jing is our most precious substance as it relates to the constitutional aspect of our physical body, i.e. our genetic material. The more well preserved our genes, the more well preserved our physical health.
The process of preserving this precious resource is essential because the Kidney Essence relates to our reproductive resources on a hormonal level as well.
Your body's hormonal status declines with age, so preventing the acceleration of this decline process is key to promoting graceful aging. Daoist cultivation practices for physical health are based upon slowing down this process.
Equally as important as the Kidney Essence is the Spirit and how it becomes embodied during the process of our physical creation.
The Spirit and Conception
At the time of conception, the Jing of both parents unites and captures the Cosmic Qi of the Spirit to be incarnated.
This Cosmic Qi contains an incarnating Spirit's Zhi, or Willpower, also referred to as the Will. This Will is the driving force behind a Spirit's incarnation and gestational development. This spiritual energy called the Zhi, or Will, becomes stored in the Kidneys upon development.
Once conception happens, the three trimesters of the gestational period unfold during which not only the body forms but also the Spirit of the baby becomes more fully embodied.
How the Body and Spirit Integrate During Gestation
According to Chinese Medicine, there are three main aspects to the Spirit, known as the Po, Shen and Hun.
During the first trimester of pregnancy, the first Spirit that gets embodied is called the Po. This is said to be the most physically dense of the other soul Spirits.
The Po is the soul that's stored in the Lungs.
Earth energy keeps the Po connected to the developing fetus during the first trimester of pregnancy. This is why it's indicated to support the Spleen, which along with the Stomach is one of the primary Earth organs, during the first trimester in order to prevent miscarriage. During the first trimester, it's also common for pregnant women to suffer from morning sickness with nausea and vomiting, symptoms that can be attributed to a weak Spleen. When the Spleen's Qi energy is very weak during the first trimester, prolapse and leakages are likely to occur, and this can lead to a miscarriage.
During the second trimester, the programming of a person's new life begins. This is the trimester associated with the Fire Element, the Heart and the Shen/Spirit it contains.
During the second trimester, the Shen becomes programmed with the life curriculum that a person is going to experience. This life curriculum contains one's purpose in life. Once this embodied Spirit called the Shen begins to gather information about one's life curriculum, the experiences needed to fulfill this curriculum begin to get programmed into the blood. This leads us to the third trimester.
The third trimester relates to the Wood element and the Liver organ. The embodied Spirit that gets stored in the Liver is called the Hun.
The Hun is like our 'collective consciousness' that contains a record of all memories - past, present and future. So as the blood gets programmed with all of this information, it gets recorded and stored in the Hun of the Liver making this organ a very important system for the health of our memory retrieval.
Once a baby is born, these three spirits - the Po, Shen and Hun - become more and more integrated until around the age of five when the process is complete.
The organ systems are in general weak and delicate until we mature. With puberty, the Kidney's Yang Qi, called Ming Men, or Life Gate Fire, also becomes strong.
The blossoming of the Kidney's Life Gate Fire is the impetus for the Zhi, or Will, to take life on as a young adult and to move the Kidney's Yin resources, the Jing, in a way that will allow one's life curriculum to unfold.
It is therefore imperative that both the Kidney Yin (Jing) and the Kidney Yang (Ming Men), both of which are related to the Water element, are abundant and flowing freely. This ensures that the Water energy will not become stagnant or accumulate toxicity so that our life curriculum, which ultimately gets stored into the level of Jing, can unfold naturally as we grow and mature as individuals.
Furthermore, when the Water energy is strong and pure it is able to properly manage the Fire energy.
If there is excessive Fire energy in the Heart, the mind will become overactive, manifesting as restlessness, insomnia, anxiety, and even mania. The excess Fire person will struggle with too many distractions and lack clarity of mind to live out his or her dharma or purpose in life.
Excessive Fire can cause a person to make choices in life that are counter to his or her dharma and thereby divert from experiencing a sense of completion in life.
On the other hand, if Fire energy is too weak, a person can become emotionally cold and not feel joy or a sense of interest in life. The weak Fire person is essentially apathetic to having a purpose at all. In this state, the willpower and passion to live are lacking or, in Chinese Medicine terms, the energy of Water and Fire are deficient.
Balance Between Fire and Water Allows Us to Stay On Purpose
A healthy balance between the Kidney's Water energy and the Heart's Fire energy ensures strong Heart/Kidney communication.
Through this interrelationship, we're able to establish healthy self-love and a clear sense of purpose in our lives.
Strong Kidney energy allows us the willpower to fulfill our Heart's desires and live out our destiny. Working together, the Heart and Kidney energies motivate us to have dreams and provide us with the drive to pursue those dreams.
Nevertheless, we have a freedom of choice as to whether to live out our path in this lifetime or choose instead to deviate and go a different way. The latter choice would be considered the result of weak communication between one's Heart and Kidneys.
Fortunately, Chinese Medicine which has created these theoretical models has also created tools with which to cultivate a strong Heart-Kidney relationship. This can be done through Qi Gong and meditation, Acupuncture, herbal medicine, and nutrition to help rebalance Fire and Water energies so that we all have the opportunity to fulfill our life purpose.
