However, it can be difficult to use both cycles, especially if one isn't sure what should be pulled in or pushed away. Using the technique that I will show here, can help make a manifestation easier to come by, and more fulfilling as well.
Magick as an Act of Sex with the Cosmos
Many high initiates of sex magick have written about the sexual nature of magickal work. In truth, the act of sex is very closely related to the act of manifesting desired changes, or magick. When using the Moon's cycles, this becomes clear as one uses the gentle "push and pull", or the sexual interplay between Mars and Venus in order to conceive a child, or manifestation.
The main idea here is that the overall intention should remain foremost in one's mind during the work so that there is no deviation from it's manifestation, no matter what current cycle the moon is in. So to illustrate the point, we'll use an example.
A Manifestation Isn't Just the Object of Desire
Let's say that one is performing a spell for a new car. During the waxing cycle, one would perform their magick to pull the car towards them, and during the waning cycle one would use magick to push "everything that is not conducive to the manifestation of that car" away from them. This keeps the car foremost in the mind, and shapes reality by carving that car from the essential nothingness.
Let's use a diagram to further illustrate.
Let the circle below represent the sphere of the desire. The dot within this circle represents the desire itself, or the specific intention of the spell. Everything within the circle that is NOT the dot, represents the environment within which the dot will manifest. Magick done during the waxing cycle pulls the "dot" into manifest reality, and magick done during the waning cycle modifies the environment that the "dot" will manifest within, by removing whichever factors are not conducive to this dot's highest and best manifestation. The dot then is the "embryo", and the entire area inside the circle and around the dot becomes the "womb".
Now since we are using both cycles of the Moon, we could even use two different spells to manifest the same very specific desire. One spell would be to draw the desire forth, and could be worked during the waxing cycle. The other spell would be to push away "what is not conducive to the desire". The second spell basically "lubricates" the manifestation into becoming, by magickally detoxifying the environment which will give the desire it's final form. The desire is the same for both, but the two approaches are essentially mirror images of each other, with one adding energy to the manifestation, and the other spell removing factors from the environment which may hinder it's best manifestation.
A Word of Caution - Use Divination!
This is a two-pronged approach that will work much better than a one-off spell, or even a week-long working. Using this technique over a month's time should bring about a powerful manifestation.
However, care should be taken to ensure that the intended manifestation is what you really want when using this technique, because it intrinsically makes modifications to your sphere that could also have other ramifications in whichever areas of your life they are also connected to.
For example, if you getting a new car requires an improvement to your credit score, you may start hearing from collection agencies or credit counselors in order to help pay off old debts and improve that score. You could suddenly have a falling out with your cable company, and decide that you no longer want their service, which would definitely free up more money for a car payment. Your significant other, who doubles as a leech on your finances, may decide that the grass is greener elsewhere and suddenly leave. One almost never knows how these things can manifest, so as always, a Tarot divination is best done before casting your spell so you'll know if you can tolerate your manifestation's most likely path of progression.
I hope this helps people understand a bit more about using Lunar cycles.
