The steps to creating positive Karma

"The thought manifests as the word;
The word manifests as the deed;
The deed develops into habit;
So watch the thought and its way with care,
and let it spring from love born out of concern for all beings.....
As the shadow follws the body,
as we think so we become."

Buddha

We have it in our power to create the causes for whatever effects we wish, with little steps (or causes) each day.
