Recently I was asked a question about how I fuel magical entities. The person asked if I relied upon deities, elemental or planetary currents or other traditional forms of fueling that are typically used with magical entities. It's a good question to ask, because there are many different ways you can set an entity up, both in terms of how you fuel it, and in terms of other specifications and customizations you can make to the entity.
While I can and do draw on more traditional methods for fueling entities, these methods are only one part of my process for fueling entities (or doing any other kind of magical work that requires a fuel source). The benefit of drawing on more traditional sources is that they are tried and true. For example if you create an entity that's focused around love, it makes sense that you might draw on the Venusian current or seek the aid of a love deity to help you with empowering the entity to perform it's specific tasks.
On the other hand, one might rightfully ask why not just go directly to the source and work with the love deity or the planetary energy without drawing upon an entity for the purposes of doing the spiritual work? Certainly that's a good question to ask as well.
The reason I choose to work with a magical entity is because I can tailor the entity toward the specific needs of the situation, which can be useful, especially if the situation doesn't exactly fit within the domain of a given spirit's influence. Another reason I might create an entity is because I want some distance from the situation, but I still want a magical working to be done, but through a lens that focuses in on my understanding of the situation. A deity or more traditional spirit may not have the exact understanding of the situation that an entity can be programmed to have...and that can be very useful with specific examples.
