When still working in IT I had a job interview where I was asked if I knew the OSI-Layers Model. I did not, and learned it by heart. Of course, I never got asked about it again lol. I recently found out after 3 years of not thinking about it anymore I still knew it through my mnemonic. To me it fits quite well next to the 8 Circuits model. As it is an Open Systems Interconnection model, which basically means the inter-operating of "circuits". Same difference.
8 Circuits/Systems/Brains/States/Stages of Consciousness
1 Physical 2 Emotional 3 Rational 4 Social-Sexual
5 Neurosomatic 6 Neuroelectric 7 Neurogenetic 8 Cosmic
Note: The following will probably make no sense whatsoever if you're not familiar with the model already, but if ye were to read up on the 8 circuit model, it might provide some enlightenment later!
The OSI Layers are a model for computers network communication, and hilariously enough - I now realize with enough flexibility (maybe enormous flexibility) one can put them side by side if you consolidate circuit 7&8 into Application hehe.
Sexual Transport: transport is also a synonym for (sexual) Ecstasy or Rapture]
Thanks for the lead Alex!
