METAPHYSICAL HACKING: How to create a Servitor or Thought-form being, otherwise known as an “Astral Entity”, to do your bidding. This practice is associated with Chaos Magick and Spiritual Egregores. Servitors are semi-autonomous beings that are summoned from what Carl Jung calls “the Deep Mind”. They are typically charged with the performance of some magickal task. In a sense these are programmed aspects of the subconscious mind, acting as extensions of you and feed off energy and desires. They are then assigned a shape, name and appearance (some activate them on certain dates and times to give them astrological properties), then a sigil/symbol/color (the Rose cross or zodical/planetary square method can also be used for that) and an energy source to feed off (ie: negativity, a light bulb, water). Sometimes we create thought-forms unknowingly due to obsessive thoughts and junk food ideas. In the case of the latters they need to be banished, as they can either help or hinder us.
