I am sure that all the positive good vibrations from the 1960's and since then have had such a dramatic and effective impact on the world. Why just look around you everyone has food - be happy - no violence in the streets - be happy - No world wars - be happy - .
Yes good intentions positive thoughts karmic giveaways, they have all had such a wonderful effect on the world as we know it.
We may as well be whistling in the wind as train with it's horn blaring passes by. They will not hear.
