Apurva

According to the Purva Mimamsa
philosophical school, apurva is an
unseen force created by action—particularly ritual action. This unseen
force exists from the beginning of the
action to the result of that action, and
it invariably brings the intended result
into being. This doctrine was developed to connect actions with their
results, particularly when the result
came some time after the initial action,
and is especially relevant to karma.
The Mimamsas developed the concept
of the apurva because they wanted to support information found in the Vedas,
which in many cases specifies that certain
actions will eventually produce specific
results. For further information see

Moore (eds.), A Sourcebook in Indian
Philosophy, 1957.
