So to be able to experience companionship oneself.

It is only partially correct that every body is (not surrounded by but) composed of karmic particles and that every body has the potential to realize one's originating cause and underwriting purpose. Truth is that every body is self not wanting to be by itself and that the purpose of self* is companionship otherwise known as love which is the why of the gospel of love (* one not wanting to be alone and that one's purpose).~ Wald Wassermann
