There are numerous magicians who make use of Lovecraft’s Cthulu mythology as a basis for the invocation or evocation of energies and beings. There are even infamous versions of the fabled ‘Necronomicon’, with Simon’s perhaps the most well-known.
Whilst in the past I may have readily decried such as mere role-play magic, I am now able to see the merits of such.
Are the beings of the Cthulu mythos imaginary? Well, they are the product of a an author writing works of fiction. Yet, where we think of something, and if any other believes in such, then we give a thing energy or life; similar to the way in which an egregore is manifest and charged. There is also the consideration that a lot of which Lovecraft wrote is very close to a number of philosophical ideas and mythological precedents. If Lovecraft denied any such knowledge of these aspects, then he was either subject to a Nietzsche like inflation by a consciousness whom wrote through him, or he was merely covering.
The implication of quantum physics suggests that by conscious observation of a result, we collapse potentiality into being. As such, we can only create that which we are looking for. This restriction may also explain why many ideas take some 60-70 years to prove; we need to look for proof of them in order to manifest such as reality. The magical result is therefore that by continued belief in the existence of the Old Ones, giving credit to the idea that Lovecraft wrote more than just fiction, then we effectively begin the collapse of potential into a manifest form. Through continued practical application of the rites of the Necronomicon, energies are given to these ‘thought-forms’ of a Lovecraftian nature. If a mere thought has the ability to collapse potential into being, then as with the biblical word of god which brought forth existence, then the readers of Lovecraft and the magicians who work with the mythos are indeed working with real beings.
Whether the beings existed prior to Lovecraft’s manifestation of them in ‘word’ is merely conjecture to any other than Lovecraft or the Old Ones. They are as real as any other conscious being of a non-manifest form on the archetypal plane.
