Practicus is a Latin word meaning, "Active".
Your entrance into the Practicus degree is marked by your learning the limitations of the Human Mind. This realization removes much of the excessive influence of the Ego.
You will experience new powers of rationalization and other mental abilities that manifest through the Soul.
In Hermeticism and Spiritual Alchemy, the work of this degree corresponds to the step of Separation.
According to the Kabala, this degree corresponds to Hod (Splendor). The sphere of the mind’s rationalizing abilities and logic.
On the level of Practical Magick, you must learn to control the element of Air and your intellectual abilities. Also, subdue the feeling of false pride, the belief that you are better than others, that often results from paying too much attention to your new mental abilities. This belief that you are better than others is a negative outward reflection of the alchemical process that is taking place within you at this stage of development.
