Along the known and unknown history, by using different methods, many philosophers and thinkers of the past have attained much higher levels of mind development than common people. Sadly, in too many cases, the essence of their knowledge and their methods have been lost, partially because the lack of disciples, partially because of difficulty to transmit this knowledge using the old existing concepts, and partially because of the adverse circumstances.

     Fortunately, some of their teachings and instructions survived up until now in different forms, such as: short stories, methods, poems or quotes and metaphors. Unfortunately, even today, most of their teachings are not completely understood because they come from individual minds with a much higher connectivity level than most people have.
