So I was going through beezlebubs tales to grandson and since there are lot of things that cannot be verified is possibly rubbish. I tend to skim through it and then the book is dense in itself.
Well every now and then few things catches eye.
It’s when Gurdjieff expresses law of octaves and existence of hydrogen as part of it. He also explains some compound that are not yet discovered but exist. These are astanine and tenessine, which have now been discovered basically in 1950 and 2010 respectively. The question is how to did he knew ?
How do I make sense of all this. I went through Walter Russel’s periodic table but even though that is close, it doesn’t wake sense. Kinda shocked confused and shaken. Help
