There is the want and desire of the medium who is being used to channel other entities, to participate in the game of the spiritual ego. There is no such thing as chance. Everything is governed by Universal Law. Even the hairs on your head are numbered, just as scriptures have said. There is nothing outside the Law.
Nothing happens contrary to it.
The Summum teachings are that humankind may use Law to overcome laws, and that the higher will always prevail against the lower. At last, you will reach the stage in which you seek refuge in the LAW Itself and laugh the phenomenal laws away.
