I have become somewhat aware of what you are talking about in the posts above. I've been wondering if the internet, devices and technology are making people lazy to the extent that they don't have to learn to spell or write properly because computers do the work for them.

I suspect that in the past telepathy was much less common than at the present so that the secrets of spiritual/Masonic science could be protected by not writing.
For some decades now the alien area of the web has referred to technology to read minds and now that discussion has come into the public domain.

In any case humans are much more telepathic these days so that it is important to veil sensitive thoughts e.g. by putting incorrect labels or images into the mental process.
