This is a sad account of a wife who committed suicide because she never felt she was doing enough. I have also witnessed this power of constant repetition and seen how it can alter people's personalities.
One bro I know calls it 'beans on toast'. You go along expecting a nice spiritual meal but all you ever get is beans on toast. Ok its boring but constantly going on and on telling people to achieve unachievable things makes them unhinged.
To a lesser or greater extent it affects all of us UNTIL we realise we are being conned. Then it doesn't affect you but if your family are still in, you have to live watching them getting damaged. That is upsetting.
