Auric Egg
Auric Egg or Envelope The source of the human aura, taking its name from its shape. It ranges from the divine to the astral-physical, and is the seat of all the monadic, spiritual, intellectual, mental, passional, and vital energies and faculties. In its essence it is eternal and endures throughout the pralayas as well as during the manvantaras.
"Every being or thing throughout the universe, and indeed the universe itself, has, or rather is, its own auric egg. Its primal substance is the akasa . . .
"The auric egg originates in the monad which is its heart or core, and from which, when manifestation begins, it emanates forth in streams of vital effluvia. On the different planes which the auric egg traverses as a pillar of light, from the atmic to the physical, each such auric or pranic effluvium is a principle or element, commonly reckoned in man as seven in number. When the auric egg is viewed on any one plane of the human constitution, we discover that this plane or 'layer' not only corresponds to, but actually is, one of the unfolded six principles of man; it would appear to be ovoid or somewhat egg-shaped in outline, and to be a more or less dense, extremely brilliant, central portion surrounded by an enormously active interworking cloud of pranic currents. . . .
"These immensely active and interworking clouds or vital effluvia are actually the pranas of the auric egg on any one plane expressing themselves as auras" (FSO 427).

Aids Glossary

Glossary of HIV/AIDS-Related Terms
ENVELOPE
In virology, a protein covering that packages the virus's genetic information. The outer coat, or envelope, of HIV is composed of two layers of fat-like molecules called lipids taken from the membranes of human cells. Embedded in the envelope are numerous cellular proteins, as well as mushroom-shaped HIV proteins that protrude from the surface. Each mushroom is thought to consist of a cap made of four glycoprotein molecules called gp120, and a stem consisting of four gp41 molecules embedded in the envelope. The virus uses these proteins to attach to and infect cells.

Envelope Definition from Encyclopedia Dictionaries & Glossaries

Wikipedia English - The Free Encyclopedia
Envelope
An envelope is a packaging product, usually made of flat, planar material such as paper or cardboard, and designed to contain a flat object, which in a postal-service context is usually a letter or card. The traditional type is made from a sheet of paper cut to one of three shapes: the rhombus (also referred to as a lozenge or diamond), the short-arm cross, and the kite. These designs ensure that in the course of envelope manufacture when the sides of the sheet are folded about a delineated central rectangular area, a rectangular-faced, usually oblong, enclosure is formed with an arrangement of four flaps on the reverse side, which, by virtue of the shapes of sheet traditionally used, is inevitably symmetrical.
