1st step to liberation - stop throwing / lofting stones in the air - they come back down ! (imagine lofting them real high so they come down further down the path, right as you walk under that path... but some thrown farther or closer down the path, no telling).
2nd step to liberation - start throwing rose petals in the air
(neat thing occurs when we evolve in these first steps)
the LAW of cause and effect
means eventually the stones from way back are diminished/exhausted (if we stop lobbing them).
BUT even more significant is that BEYOND LAW is DIVINE GRACE...
it is like an umbrella
it might act like a filter and protect us from big boulders or rocks, and only let little pebbles or rose petals thru...
When we we understand the notion that what comes around goes around we usually do what is in accordance with divine law to avoid the pitfalls of karma. It seems to me that most of us that are reading this post create karma because they are not able to always distinguish what choices are best for the situation. There are many situations in life that are grey in nature. For these situations we are effected and the people around us are whether we make a choice or do not. In this sense i do not find your analogy holds up Scott. Sometimes we hold heavy flowers and very light rocks. We are blinded and we do not know what to throw up on the air. If we throw nothing the law of karma effects us for taking no action when we can not stand still and wait any longer.
