The difference between spiritual atmospheres and physical atmospheres is that spiritual atmospheres are vessels of divine fire and light, of love and wisdom, then. They bear these things within themselves. Physical atmospheres, though, are not vessels of divine fire and light; they are vessels of the fire and light of their own sun, which is intrinsically dead, as explained above (Sections 89, 157–159).
As a result, there is nothing from the spiritual world’s sun within them. However, they are surrounded by the spiritual atmospheres that come from that sun.
This differentiation between spiritual atmospheres and physical atmospheres is a matter of angelic wisdom.
