Seed
[encyclopedic theosophical glossary]
The essence or germ of an entity, imbodying its svabhava (essential nature) and determining the forms produced from it, partly by the accretion of various elements but mainly by the emanating stream working from within outwards or above downwards. The seed of a plant is a globule of physical matter, but the actual seed is ultra-physical. All seeds strictly speaking are the vital life-forces working in and through the physical germs, and hence these true seeds are ethereal organisms, structures composed of a higher order of matter (SD 1:201). Thus there is a succession of vital seeds pertaining to one individual entity, each such seed being the ultimate unit of that organism on a particular plane. There is the physical seed of a plant, containing the astral seed -- a unit on its own plane containing a still subtler seed belonging to a higher plane, and so forth. Ultimately a seed is a life-atom, in itself the expression on a particular plane of a monad which is a thought in divine ideation.
