This can be done for purposes regarding one's own life. If the theories about the evolution of the spirit are true then it may be possible to create change in one's life just by thinking about conditions and trying to understand them. To better understand what that means, let's summarize spiritism in the sense of evolution of the spirit.
Spiritism says that every person comes to this life (reeincarnation) over and over to evolve and understand. This understanding covers everything in one's life. The conditions in which a person lives is determined by the terms according to his/her specific needs for evolution of his/her spirit. And when the person understands his/her lesson on that particular subject, conditions change.
So, for example, assume that you are in a relationship which goes really unhappy. If you take the time and meditate on your relationship with a question in mind such as "why, why on earth do I have to live through this" and if you can achieve to understand the message there, your relationship might change.
By saying "message" I don't mean a new agee approach. First of all, there is no single message in one's life span and there is no single aim of life, at least in my opinion. What I mean is a real advancement of your psyche. According to spiritism, you come across events where your spirit will be developed by them. If you try to speed up the process in which you get the hang of things a little faster, then your life will unfold towards better experiences. At least on those areas where you "suffer" now.
Since this work leads to a change in your environent and in events, people, etc. you are surrounded by, you can call this magick too.
Happy new year, by the way.
