We can change our reality by changing our minds about things. If someone harms us, we have a choice of hating them and expending lots of energy contemplating revenge or self-pity, or forgiving them and letting that energy be used for more constructive purposes. If our beliefs cause us to be defensive or overly critical of others, becoming more tolerant and understanding of other people's beliefs may make our lives more peaceful and joyful.
I wish for you a life filled with love, joy, peace and prosperity, secure in the knowledge that there are many ways of looking at life. You have the ability to create the best possible life for yourself.
