Full Idea
Being is everywhere thought in, foisted on, as cause; it is only from the conception 'ego' that there follows, derivatively, the concept 'being'.
Gist of Idea
We get the concept of 'being' from the concept of the 'ego'

A Reaction
'Being' is such a remote abstraction that I doubt whether we can say anything at all meaningful about where it 'comes from'.
