This image and it's meaning considerably deviates from the standard Rider-Waite. Many of the cards in this deck are reflections of what Pollack has seen and heard on her world travels. In this case it is the Australian land, sorted by song in the Aboriginal tradition rather than war or maps.
I'm reminded by this card of 'close talking'...something characters on television do, often just inches from each other. It probably has to do with camera angles and close-ups, but in real life people wouldn't stand for it; two or three feet is more like it. Respecting those boundaries is something we do instinctively with every conversation we have.
