Quote:
If the past 50,000 years of mans existence were divided into lifetimes of approximately 62 years each there have been about 800 such life times. Of these 800, fully 650 were spent in caves. Only during the last 70 lifetimes has it been possible to communicate effectively from one lifetime to another – as writing made possible to do. Only during the last 6 lifetimes did masses of men ever see a printed word. Only during the last 4 has it been possible to measure time with any precision. Only in the last 2 has anyone anywhere used an electric motor and the overwhelming majority of all the material goods we use in daily life today have been developed within the present, the 800th lifetime.
