I'd like to know the precise meaning of "communicated" in the following excerpt from the Chapter Eight of The Great Gatsby:
They had never been closer in their month of love nor communicated more profoundly one with another, than when she brushed silent lips against his coat’s shoulder or when he touched the end of her fingers, gently, as though she were asleep.
Does it mean "understood each other"?
On the last day before Jay Gatsby is shipped out, he sits with Daisy in his arms for "a long, silent time." They are calmed, surfeited, in this afternoon as though time poses for their memories.
Now and then she moved and changed his arm a little and once he kissed her dark shining hair.
This moment in Jay's memory is one of significant eroticism and romanticism. They communicate "profoundly" in this erotic moment, their bodies fused in young passion. This closeness is not one of understanding; rather, it is one of shared physical union. It is in this physicality that Daisy and Jay are close, and when they are separated from each other, this emotion fades and the object of Gatsby's desire becomes unworthy because it is reduced to materialism when Daisy accepts Tom Buchanan's pearls and "shapes" her life.
