What Does This Living Hand Represent?

I think in the poem "This Living Hand," Keats uses this image of a hand to symbolize life and death. The "warm and capable hand" invokes a happy and calm emotion contrasting with the "cold" and "icy silence" which give the image of death. Keats also uses the word "if" suggesting that the hand is still alive and capable of loving since in the line, "so haunt thy days and chill thy dreaming nights" could possibly suggest that even those that have died are still with those living. In the final line, "hold it towards you" suggests by taking the hand, you are not embracing life or death but acknowledging it.
