"Ice cream" makes me happy, but I know there are people out there who dislike it very much. Happiness is a state of mind that causes your vibrations, your frequencies to rise greatly . . . and that's a good thing! Do you think that we (humans) were created to be "happy?' I'd like to think so, but if that were the entire truth, why is anger one of our emotions? I guess it's because we live in a universe where opposites are part of our existence. You know, Yin and Yang . . . you can't have light without darkness, up without down etc.
I suppose it makes sense when you take in to account that there is a dark side of happiness too. While most of us find pleasant things to make us happy, there are evil, deplorable, people in the world who find happiness in causing harm and pain to other people and the things around them. However, I choose NOT to focus my attention on any form of negatively charged happiness, but only the kind that brings joy, laughter and love.
As a matter of fact, here are a few wonderful reasons for me to be happy. I have plenty more, but it would take me all day to list them . . . and probably fifty pages!
