All of us have habits or tendencies that bring us suffering. Though repeatedly we may try to change these patterns, they follow us around like a cloud of gnats. This is the result of the law of karma: Every action we take is a cause that has an effect, an effect that sometimes follows us even from lifetime to lifetime. These effects can be good or bad, freeing or binding, depending on the action involved.
This insight has great importance for all of us seeking soul freedom. We mistakenly think that the chains of karma keep us forever bound in delusion, when, in truth, we have the power at any time to make the kind of choices that will set us free.
There is a story about a saint who was peacefully meditating under a tree along the banks of the Ganges. At a certain point he heard a rustling overhead and opened his eyes to see a large scorpion moving along a branch overhanging the river.
