Well, unfortunately your chart has expired. You really need to upload your chart here as an attachment for it to stay. If you want, you can send me your birth info as a pm and I can take a closer look. However, yods are very personal and without actually sitting down with you face to face it's very unlikely that I'll be able to decipher your yods by just looking at your birth chart. Also, I'm a beginner in astrology. That being said, it was my yods that brought me here ultimately.
IMO, Yods usually produce the desire for the native to "search" for something. This desire is produced by the energies that the quincunx aspect puts forth which asks the native to make an adjustment in their life. When two quincunx are funneled together to form a yod, the adjustment nature of the quincunx is increased exponentially. This then produces an irritation of sorts, or maybe an itch that needs to be scratched type phenomenon. In my view, the native usually already knows what is required to appease these energies but may not be acknowledging them properly or at all. Herein lies the unbelievable strength of the yod, for if you start venturing in this path much can be gained.
I encourage you to search this forum as well as the internet about yods and gather as much information as you can. Get to know what the apex planets mean in their houses and signs. Explore different house types to make sure you are using the most accurate one for your chart. I prefer equal house, but many here use whole sign and placidus.
You have what's known as a bathtub formation according to huber astrology. The hubers did quite a bit of work on aspect pattern astrology and the quincunx aspect:
...The bathtub shows the constructive attempt not to "let the tide go out". In psychological terms, people with a bathtub in their horoscope aspire to keep what they have at any price. They cleverly avoid losses, want to keep everything together and make every effort not to dissipate their energies... The two internal green aspects give the persona a tendency to subjectivity and sensitivity when evaluating perceptions. Because of their own naivety, they tend to see things too positively, to rosily, they are too trusting... Like a cupping bell, this figure has the tendency to draw and suck everything towards itself, so that the person often feels exhausted and without energy... The learning in this figure is characterized by long and hard experience, as well as a certain reluctance to learn...
The Hubers on the quincunx aspect:
The "long green" aspect causes insecurities on the one hand and on the other the urge to achieve an imagined future goal. Sometimes it is also called the "longing aspect". It often brings decision crises, uncertainty, and eventually the challenge of restricting oneself to a single goal, in which case it aids decision-making. It is called "the large thinking step" and, according to the planets involved causes a "Faustian struggle" with the truth.
According to Joan Kellog in, The Yod: Its Esoteric Meaning, here is some of what she says about your Saturn apex yod in the 5th (She refers to the apex as the foot and the midpoint in the sextile as the activating point):
An individual with an eleventh house activating point has to develop interests within a group, to experience life as a mutual participant, not as an observer. This axis of awareness indicates a person with marvelous group facilitation and management skill potential but who feels uncomfortable within the confines of a group. The fifth house foot has a natural reticence to relinquish its coveted privacy, it insures one a criticism-free environment. But it si only through group work that one's true service emerges. This axis of awareness truly represents the lesson of the New Age: group service.
12th house apex (I'll include one paragraph out of about eight):
With a sixth house activating point, the individual must develop a less critical nature, one that synthesizes and produces constructive results from corrected conditions. This is a very difficult lesson because the foot, located in the twelfth house of karmic and fateful conditions as well as the unconscious mind, has a tendency to keep the individual off balance with the deep unconscious needs of others. The Piscean need to lose oneself in service to others, martyrdom really, keeps the individual off track. The great world suffering prevents the individual from seeing his small but important part in alleviating that suffering. It is almost as if the sea of humanity is calling but he forgets that there is sickness at home where he is needed first. These individuals need to develop realistic perspectives and discrimination - a mercury lesson...
Kellog also writes of the yod:
The yod configuration represents a specific mystery, containing within its geometry a key to a spiritual or karmic lesson that must be learned before its power can be released. The mundane karmic lesson is represented by the foot and the esoteric mission by the activating point.
One thing that I have started to do is to really follow transits. They have illuminated much about what my yods are about. As you can guess, transits opposing the apex are the ones that are really important. In an aspect pattern such as yours, any transit will make your whole aspect pattern "blossom" with that energy. Much insight can be gained.
Please excuse any misspelling and there is a chance of grammatical error since I relied heavily on computer correction. If you have any questions let me know...
