Between 6:00 and 9:00 position of our yin-yang symbol, we enter another dynamic transition of the menstrual cycle. I consider this the most magical, and yet most invisible aspect of the fertility cycle. Yin has transformed into yang through the process of ovulation. Under the influence of LH, the follicle has transformed itself into the corpus luteum or yellow body, which secretes progesterone for a pre-programmed 14 days, or half a moon phase. This “yellow body” bears the color of earth, to which the spleen belongs, which governs the endocrine function of progesterone’s holding effect. The spleen meridian runs through the ovary. The egg has been released, the fimbria (or fingers) of the fallopian tube has picked it up, and if sperm have made it through the vaginal canal, cervical opening, up the uterus and into the tube, fertilization is possible. If fertilization takes place, one cell becomes two, and the zygote, which means “union,” splits. Here the central tai ji pole, or original chong meridian, opens to heaven, where, the Taoists describe a poetic vision as the big dipper pours the essence of the stars into the new individual to provide it the spiritual essence for its upcoming life.
The liver meridian runs through the fallopian tube. When its qi is unobstructed, fertilization is more likely. Liver qi stagnation can cause the fallopian tube to “clench”, and even may end up showing a false positive in an hysterosalpingogram.
In our reverse cycle energetic, required to create an individual through the pre-heavenly essence or prenatal creation, the liver directs its energy to the kidney, as blood feeds the essence. The kidney grasps the qi. The penetrating (chong) meridian arises from the uterus; and is the envelope through which consciousness chooses expression. According to the Ling Shu, (Spiritual Pivot, 1st Century BCE), every day of the menstrual cycle, the qi descends via the Governing meridian, one vertebral process per day, until day 21, when it enters the chong meridian, which allows the mingling of heart fire and kidney water. If the parents essence have ignited the cosmic qi (or if the cosmic qi has allowed the parents essence to ignite…) the entrance of a new soul will enter into manifestation. This is the time of implantation. The palace of the child must communicate with the embryo, which is also emitting chemicals calling for a home. The endometrium expresses proteins that let the embryo know, “you have a home here.”
Held anger blocks the liver-kidney conversion. Excessive worry and anxiety can inhibit the spleen qi’s holding ability. What can you do to help this process most? Stay out of it. Nature did not intend for your involvement at this time.
If this magical union takes place, the lung (whose highest function is “releasing”,) directs prenatal creation as it calls the corpus luteum into increased production of progesterone to uphold the embryo during the first ten weeks, at which time the placenta will take over its function.
If the cosmic qi is not ignited, the lung directs a new cycle to begin; the uterus discharges its blood and a cycle of hope is renewed.
