That the better the poet the more verses will be better?
Sure.
However, if you’re talking about the Eastern practice
of mulling many verses over tea: No. I drink Cuban coffee
(from Columbia).

Otherwise existence = the universe of matter
(what the universe of energy extends to is
"for you to find out").

    Thank you, Herb: I was born without any arms
    so I had to learn how to type with my tongue
    (which gave me a tasteful way of writing).

    PS. Had a uncle was born with arms once
    but apparently one of’em was loaded and
    almost blew away my grandmother’s ass! "Never
    again!" (Swore the rest of my family. This might
    also go a long ways toward explaining why
    most of the rest of us were also only born once.)
    But, who knows!
