We may think that happiness is an acquisition, and therefore buy more and more things. Soon we observe that depending on the momentary high experienced in an acquisition is truly temporary, and that in order to stay happy all time, we would have to acquire a never-ending stream of objects. We also might think that another person gives us happiness by paying attention to us. Again, this would mean a person would have to be focusing on us all the time, in order for us to feel happiness all the time. Neither by trying to acquire a stream of possessions, or by constantly expecting or trying to coerce a person to focus all their attention on us, do we experience a baseline of happiness.
Happiness is the outcome of harmony.
And, harmony is the outcome of living moment to moment in alignment with the highest good of the moment. When we live peacefully and usefully, we are living harmoniously we feel happy. So, happiness is with us all the time as a state of our own being brought to the forefront in our lives when we are living harmoniously in the world. In this realization we can see that each of us has happiness ever available, from within ourselves, experienced when our attitudes, decisions and actions are in harmony with peacefulness and goodness.
