“My holy Self abides in you, God’s Son.”
As the Source of Creation (the Father, God) expands, It moves into extension (the Son). Just as a poem expresses an underlying idea and is unthinkable without it, so does the Son express the Source of Creation and is unthinkable without the Source it gives expression to.
All that you experience is Source in extension, each individual aspect imbued with Source’s true nature and proclaiming it to all others aspects.
