The secret to happiness and inner peace is thus not just the Law of Attraction and being mindful of our thoughts, although this is certainly important. The secret is being mindful of our actions as well, because just as our thoughts condition our behavior, our behavior conditions our thoughts, and regular daily actions of instigating violence and eating the results of that violence keep our consciousness and thoughts confined to a relatively low vibrational level.
