Step 1: Understanding the Concept:
This is a question about a simile used in the poem 'The Sleeping Porter' by Laxmi Prasad Devkota. A simile is a figure of speech that compares two different things using 'like' or 'as'.
Step 2: Detailed Explanation:
The poem describes the porter sleeping, exhausted from his labor. The poet describes his physical state in detail.
To convey the fragile yet persistent nature of his life, the poet uses the line: "His heart is twittering like a bird."
The sound 'twittering' is uniquely associated with small birds. This simile suggests that the porter's heart is beating faintly and rapidly, much like a small, delicate bird, emphasizing his vulnerability and physical weakness.
Step 3: Final Answer:
The heart of the porter is twittering like a bird.
