There is only one desire to receive, but it manifests in many different forms, including the present, final form that we feel today. All of our sensations are nothing but the desire to enjoy which has many different facets. I see a world full of people, myself in it, and many other things, actions, causes and consequences. It all amounts to the same desire to receive that exists in the spiritual world.
It’s only that in this case, it assumes a “material” form which we call a human body. The higher form is what we call a soul, but in any case, we’re speaking strictly about the desire to enjoy.
All the degrees are identical in their matter (desire) and fulfillment (Light). Only the last, lowest degree differs in that it imparts to man a feeling of separation from all other degrees or leaves him without this feeling altogether in the reality of this world. This degree has its own details of perception, but even they are perceived in relation to the desire to receive and the Light which exist at their lowest state.
