There are many different types of Circle, each circle has a purpose and will be formulated according to it's aim. The Circle has its roots in tribal custom where people sat in a circle to indicate that everyone has the opportunity to take a equal part in the proceedings. Circles range from open through various development circles to physical phenomena circles. We are interested in Beginners and Development Circles.
You must remember that Circle leaders and existing circle members have the right to say they do not want you in the circle. Do not take this to heart, there are a myriad of reasons why people are rejected by circles. Usually you will find that, as in life, there are some people you do not gel with. Fortunately this has been recognized by the circle leader or group and they have said no. To try to sit when members do not get on well together will eventually lead to factions within the group. What is important within a circle is that everybody trusts each other and no one must harbor bad feeling towards another. The other possibility is that you may feel uneasy with one person in a group. In this case it is your responsibility to say so and not join that group Having said all that it is unlikely that it will happen but if it does it is not your fault or circles fault it just happens move on.
Once you are in a development group, try not to judge your progress by others and how they are doing. We all come from different backgrounds, we all have a different job to do, so we all must develop the skills we need, not the skills as someone else potrays them. The best way forward is always to understand that you must do what is right for you.
