I actually find this to ve a great example of how cadent houses can express their apparently "negative" influence in a positive way. A certain characteristic of an astrological element should be examined thoroughly and by respecting all of its characteristics. And,in my opinion, this doesn't apply only to cadent houses but also to "malefic" planets, stressful aspect etc.
In different types of chart delineations, we concentrate on the most important value of a certain element however, in very detailed analysis, such a the delineation of a Natal chart, we need to respect all of its meanings. Obviously, the cadency supports certain inactivity and is often assigned a few negative meanings but, without cadent houses we'd have no nurses to take care of the patients, we'd have no hospitals, no spirituality, no literature, no buyers and clients... Such activities require the type of energy suggested by cadent houses! And, whilst it can be rather frustrating to have the ruler of your ambitions trapped inside a cadent house, we also need to keep in mind that a care-taker can only provide help inside the 6th and the 12th as that is where people who need help reside.
Like I said, there are many other examples in astrology where we need to adjust our approach to a specific element from different angles, each time respecting a specific quality of that same element. Pisces, for instance, is fruitful sign and, having Venus there can sometimes be very good in a chart of an artist however, if that artist wants to be be a singer then we have a problem since Pisces is also a mute sign. Due to its double-bodied nature, Gemini can sometimes suggest multiplicity however, it can also suggest barrenness.

Cadent houses don't necessarily stand as blockages; depending on the aspects and the rest of the chart, they are sometimes simply the indicators od the type of the surrounding that the Querent is most likely to have or the type of activities that might be important in their life. If someone wants to be a monk whi dedicates his life to meditation, spirituality and search of the higher knowledge then, we can'rt really expect his chart to have prominent angles, can we? But, he will still enjoy his cadent life.

As I recently have read (don't remember where, my Mercury is in cadent 12th, lol (it may well have been here on the forum!)), the so called "weakness" of cadent planets has a lot to do with diversity and lack of consistency. Cadent planets are not per se weak, but, er..., trying to multitask as it were. No gush of action in one direction here, as in the pivots, no result built up by consistency as in the succedent houses, but a lot of diversity and therefore splintered energy...

But..., as in traditional Feng Shui is taught, one has to USE the available, or "given" qualities, to make them work! Meaning, using Jupiter ruling 2nd house and placed in the cadent 9th for study and practice of spirituality or higher knowledge or travelling abroad, his so-called weakness by house-placement would be redeemed by Jupiter being assigned a job he loves/needs to do!

As I understand this, it amounts to "humouring" the planetary spirit for the task he's given in the natal chart; he/it/she will then be happy, and "perform"...

I think that is a very neat answer and I agree with it. Another thing I think that's important to bring up about joys in cadent houses is that cadent houses can allow malefics to run amuck, which is probably why the malefics joy there in the first place. Saturn joys in the 12th because he is free to cause mischief unhampered, Mars joys in the 6th so he can beat his workers/slaves to produce more (wealth) for him. The Sun can be malefic and joys in the 9th house by spreading belief in himself all over/be boastful/possess a sense of superiority.

My Sun is peregrine in the sign of Gemini, but it placed in the Sun's joy of the 9th house. Some people have interpreted that as the source for my "strength," but I've always disagreed with that. My Sun receives trines from angular Libra Jupiter+Saturn placed in 1st house. Exalted Saturn does give my low powered Sun a lot of backbone where I exhibit some strong leadership qualities, but I'm not a Sun person. If anything, I'm rather anti-Sun and cannot stand those who are Sun-like in personality (managerial, showy, bossy, egotistical, prideful, etc.) But that's because I have exalted Saturn doing something drastic to my Sun and coloring the Sun to take on more Saturnine qualities. However, having the Sun in its joy is a blessing, as I've always believed in myself and so have strangers who have often taken a liking to me (for no apparent reason).
