It means that beautiful things owned by someone doesn’t necessarily represent that persons insight, or wisdom.
If anything, some of these people have become a slave to the beautiful things which they own.
Materials can often cripple their connection to Source wisdom, which can hinder or distort the beautiful things spoken.
On the other hand a person with a beautiful soul, doesn’t need to have material things to showcase their gnosis or the beauty that is within Being.
That person is living from a deeper space, that person is a cosmic co-creator becoming a muse unto themselves and then the ones around them.
The beautiful things said come from a deeper connectedness to Source so therefore the beautiful things drip from their lips like honey.
