Since the conceptions of space/time, or physics, and time/space, or metaphysics, are mechanical they are not central to the spiritual evolution of the mind/body/spirit complex.
The study of love and light is far more productive in its motion towards unity in those entities pondering such concepts.
However, this material is, shall we say, of some small interest and is harmless.
~ Law of One, Sept 9, 1981
That self-doubt arises in your thought patterns will not mean you have cause for self-doubt.
You have no cause for self-doubt because you have no cause for fear.
To dwell in fear will end your ability to dwell within the love that is Christ-consciousness.
Jesus, A Course of Love T4.12.11
Spirit preceeds Inspiration
Inspiration preceeds Imagination
Imagination preceeds Belief
Belief preceeds Form
~ Jesus, A Course of Love
My dear brothers and sisters in Christ, as you once willingly resigned as your own teacher, I now willingly resign as your teacher. In unity there is no need for teachers or learners. There is need only for the sustainability of Christ-consciousness in which we exist together as creators in unity and relationship.
Jesus, A Course in Love T4.11.3
