In any spiritual development, individual work is paramount. You cannot achieve any inner development without a proper individual work that takes place over a long period of time. Sporadic rituals or psychic practices are not enough if we want to really achieve something. There is no question.
However, it is obvious that there are things that cannot be done alone. As a single man cannot build a pyramid, many men can. What is true on the physical level is also true on a spiritual and magical level. If you decide to perform a ritual for a specific purpose, let’s say, find a job, you relay on a few things: your knowledge of rituals, your ability to use your inner powers and the cosmic invisible energies. This is the first challenge, but you can decide in the name of individual freedom that you will not join any other individuals. This kind of choice must not be challenged.
