Over the years I've encountered more than a few discussions about the space one uses when conducting magical operations. More than a few beginners frighten over the fact they don't have a place to use solely as a temple, in the actual sense of the word. They consider this a liability and worry over the fact his would hinder their work, as in their results would be weaker.
Moreover, there are many out there who stress over the importance of a temple space. Often, these people happen to be in the business of crafting and selling magical implements, from something as complex as Golden Dawn temple pillars to something as mundane as candle holders one can find at garage sales. With their profit in mind, it seems obvious such people keep spamming the alleged importance of having as pristine a temple decor as possible, with every imaginable paraphernalia on the side.
In reality, this is not a must! While having a specially dedicated room as a magical temple would be ideal, most people cannot afford it due to obvious financial and social reasons. Therefore, a ritual space is required for undergoing magical practice. This space can be anywhere on the property or in nature, whether it be a kitchen, attic, back yard, the local woods and so on. So long as it allows the person relative peace and quiet for the duration of the work, it should do.
