In the book "Glittering Images" by Susan Howatch, a powerful metaphor is presented through the quote about acting as a porter. The imagery of a porter suggests the idea of helping others carry their burdens, making life feel lighter and less overwhelming. It emphasizes the importance of sharing emotional and psychological loads with someone who is willing to assist.

This notion encourages individuals to reflect on their challenges and consider seeking support from others. By unloading some of their struggles onto a trustworthy person, they can alleviate the strain of life's demands and experience greater ease in their journey.
