For instance, "furling" wings could imply:
* A transition into a state of rest or dormancy: Like birds migrating for the winter, the soul is preparing for a period of introspection or inactivity.
* A withdrawal from the world: The soul is detaching itself from earthly concerns, perhaps in anticipation of death or a spiritual journey.
* A sense of loss or limitation: The soul is being constrained, perhaps by the approaching cold or the limitations of the physical body.
Knowing the full poem and its overall theme will be crucial to understanding the specific implication of those lines.
