Shuffle Off This Mortal Coil. It's a quote from Shakespeare's Hamlet, where there is a reference to shuffling off this mortal coil, meaning separating soul from body, i.e. dying. Our mortal coil is our body. Mortal coil is a simile for Life. Mortal coil is a poetic term that means the troubles of daily life and the strife and suffering of the world. It is used in the sense of a burden to be carried or abandoned, most famously in the phrase shuffle[d] off this mortal coil from Shakespeare's Hamlet. (For more context of the phrase, see To be, or not to be.)
