Energy is a Synonym for Self.

The word energy (E) is a synonym for self (I). So when we physicists state that 'there is only one energy' and when the poet states 'there is only one self', we are in agreement with each other. There is but one energy or one self which animates itself this for the purpose not to be by itself. The purpose of self companionship. The purpose of self friendship. The purpose of self love.
~ Wald Wassermann, Physicist/Poet
