Candle magic idea for multi-house astrological elections
The idea is quite simple and is based on the logic described in the Picatrix and De Imaginibus of establishing a celestial link for two things for which one wishes to establish an earthly link.
In this type of election, the main requirements involve a) strengthening the lord of the Ascendant, which represents the magician or the person to whom one wishes to benefit, b) strengthening the Lord of the House which represents what is desired, and c) placing a positive aspect between them. Thus, to symbolize this type of relationship in a magical working you would take a candle of the color related to the planet that rules the ascendant and a candle of the color related to the lord of the house in question. You would write your full name on the first candle, and the name of what you desire on the other. You would anoint both with an oil that represents the type of connection you want to establish (love, prosperity, etc.) or an oil that represents the Lord of the Ascendant itself. Finally, you would reinforce this link by tying the two candles or their holders together with a string of some relevant color before lighting them.
This type of work could be complemented in two ways - lighting the candles on a round plate on which you have written the symbols of the planets and their positions according to the angles they are in on the astrological chart, or literally printing the chart beforehand and lighting the candles on it. Additionally, before lighting the candles (and reciting some prayer, hymn, etc.), at the relevant time of the election you would draw a talismanic image or write a petition on a piece of paper, and then light the candles on top of it. Using tarot cards or regular playing cards could also do the job.
