As for needing preparation, you never know. It may help and it may not. The challenge is knowing what is the preparation for the extraordinary to be received. I have found that the main preparation is the doing. I recall being in a group experience in which I was very involved and I was cocreating the experience while simultaneously being impacted by it. My realizing this was minimal as it was happening and became clear afterwards. What helps me remain aware that I am both a composer of the group field and part of the composition is knowing that all that is is inseparably interconnected and correlated. How could being both composer and part of the composition be otherwise?
