This is all fine and dandy, but what happens if Jupiter happens to be in bad dignity? Jupiter is now debilitated in Capricorn and will be so until later in the year. Venus is a few days away from exiting her sign of detriment, Aries, where she spends around three weeks. What if you cannot wait for the planets to become more powerful in the heavens and you just have to solve your problem there and then? What happens if they also happen to be involved in hard aspects with the likes of Saturn (Mars, or the outer planets - I do not care if some people do not consider them as well!), especially when they're transiting a sign in which they are weaker? What happens if the spirits of the Goetia only provide you with just a teaser, so to speak, and instead of getting the amount of money you desperately need to pay your rent, you only get enough to buy a pack of smokes? Because they can do that, because reasons...
Well... you just have to look for help elsewhere, and for that you need to widen your perspective on the spiritual world. The Western Magical traditions employ the use of a wide variety of spirits, be they celestial or chthonic, and sticking to but a few will only get you so far in your endeavors. There's the angels of the zodiac signs, zodiac houses, the Shem angels, and the spirits of the four elements (who's kings are <as per the Golden Dawn> Djinn, Niksa, Paralda, and Ghob). There are also spirits mentioned in particular classic grimoires and magical systems found in the grimoires. For instance, the Enochian King of Friday can be employed for operations having to do with air, which can prove to be a great asset when you want to perform weather magick.
Let's say you and your romantic partner are going through some rough times and you want to improve that by making use of magick, but Venus has just entered Aries, Scorpio, or Virgo. What do you do? You can call on the angel of the seventh astrological house, for instance. The seventh house deals covers relationships and partnerships, among other things, and it also happens to be the house of Venus. I am not going to go into detail about how to benefit from the forces of the seventh house to a greater extent using astrological elections, but you can call on its angel for assistance and help with your issue regardless of Venus' placement and aspects. You can also call on the elemental king of Water for that. Another good example: you are a researcher in a lab, and you want to take your work to the next level, but Mercury happens to be in its sign of both detriment and debility, and retrograde, just as it happens to be while I'm writing these words. You can call on the angel of Aquarius, the elemental king of Air, a few Shem angels, and a few spirits of the Goetia, to name but a few options.
There is the case where spirits also have the power to take away that which they can provide. Spirits of Venus can bring love between people, but they can also take it away, and sow hatred, envy, and jealousy instead. Spirits of Jupiter can help someone obtain a promotion, but they can also demote them. And the list goes on... And there is also the case where certain forces can help you with things that apparently are not in their power. There is a Saturn talisman in the 6th and 7th Book of Moses which can help someone win at gambling, and if I'm not mistaking, the Picatrix also talks about Saturn being able to provide one with money and wealth. So yeah... people just have to become aware of more possibilities when it comes to working with spirits, in my opinion.
If someone were to ask me how they can come across the best spirits that will help them in certain situations, I would tell them to look for themselves, because a spirit will not work exactly the same with two different people. There can be many similarities, but each human-spirit magical operation is unique in my opinion, for reasons I am not going to go into here. I would recommend, though, that the person call on Hecate and ask her for direction towards spirits that can provide with the best help possible based on his or her problems.
I don't even know why I've written this, but it's done now.
Hate on, dum-dums!
