What's done has already been done. Stop it if possible. What can
be done is to generate merits and dedicate to the
animals and do self-repetance.
Switch to a new job if possible. Even if we dont talk about any
dharma , karma will still exists.
Below is notes from my lam-rim class:
THE 4
GENERAL CHARACTERISTICS OF KARMA
1) The Certainty of
karma:
positive and negative deeds will definitely
plant seeds that will bear respective fruits.
2) The Increase of
karma:
one seed produces many fruits, each of which
has many seeds of a like nature.
3) Actions not done
do not bring results:
if the cause has not been created, the result
will not be experienced; a deed (+ve or -ve) not done produces no
result.
4) Karma once
created will not disappear of its own accord:
every deed of body, speech or mind leaves a
karmic seed in one's mental continuum that is never exhausted
(unless purified).
