The Law of Cause and Effect states that for every cause there's an effect.
In life, our thinking is the cause and our experiences are the effects of our thinking.
Attempts to change our experiences are merely a band-aid solution because all negative experiences are merely the effects of our thinking.
So if we want to change our experiences, we must begin by changing our thoughts.
If you have read my book Feeling Good, you will know that prayer is one of the most powerful tools for shifting the direction of your thoughts.
