This is what was understood to be the Astral Body.
The astral body is sometimes said to be visible as an aura of swirling colours.[5] It is widely linked today with out-of-body experiences or astral projection.
Yep. Some traditions even have two parts for it, one that passes on and one that decomposes with time... In the Chinese systems this one is called Po if I recall correctly.
