What is the meaning of mantle and mantle?

Could you please clarify the significance of the term 'mantle' and its potential meanings? I'm a bit perplexed as to its various usages and connotations. In the context of the paragraph, it seems to carry a certain weight, but I'm not quite sure how to interpret it. Could you elaborate on its usage, perhaps with some examples? I'm eager to understand its subtleties and how it fits into the overall narrative.
