Yes Johanna; Richard’s point has to do with a metaphoric reference. Joseph in the below clip describes this further in the clip below as a: “category” of thought. Being and non-being he describes as categories of thought; constructs of the human mind that are located within the field of time which he defines as dual. Light and dark; good and evil; and so on because they are opposites and therefore fall into this mode of thinking because human consciousness has created this construct.
Because this format only takes one link at a time without pausing for a moderator to check it for outside spamming possibilities I will post a second clip in a second post where he describes this mythological insight and understanding further.
