34. From Secrets of Heaven
Things that are true on a spiritual level cannot be grasped without knowledge of the following universal principles.
1. In order to be anything at all, each thing in the universe must go back to goodness and truth and their partnership, and therefore to love and faith and their partnership.
2. We humans have will and understanding, the will being the part of us that is receptive to goodness and the understanding being the part that is receptive to truth. Everything in us goes back to these two and their partnership, just as everything [in general] goes back to goodness and truth and their partnership.
3. There is an inner self and an outer self, as distinct from each other as heaven and earth, and yet these two need to become one if we are to be truly human.
4. Heaven's light is the light that surrounds the inner self, and this world's light is the light that surrounds the outer self. Heaven's light is divine truth itself, which is the source of all intelligence.
5. There is a correspondence between what is in the inner self and what is in the outer, which means that what is in each comes out in a different guise in the other-so different that we cannot sort them out unless we know how this correspondence operates.
Unless we are aware of all this and a great deal more, the only concepts of things spiritual and heavenly we can grasp and form are incoherent. This means that the facts and experiences of the outer self, divorced from these universal principles, cannot be useful to our rational functioning for learning and growth.
We can see, then, how necessary information is. There are treatments of these universal principles in many places in Secrets of Heaven.
