Definition of "etheric"

"It is usually allowed that there is the natural body, as St. Paul called it, which is dissolved at death, and the etheric or spiritual body which survives and functions upon an etheric plane."

Most commonly spirit beings appear in their etheric bodies, but there are many accounts of these old sorcerers calling up spirits in their fleshly bodies[.]

1936, Rollo Ahmed, The Black Art, London: Long, page 229
