The incarnating entity which has become conscious of the incarnative process and thus programs its own experience may choose the amount of catalyst or, to phrase this differently, the number of lessons which it will undertake to experience and to learn from in one incarnation. This does not mean that all is predestined, but rather that there are invisible guidelines shaping events which will function according to this programming. Thus if one opportunity is missed another will appear until the, shall we say, student of the life experience grasps that a lesson is being offered and undertakes to learn it.
