The author has used gentle humour to point out human foibles. Pick out instances of this to show how this serves to make the piece interesting.

In literature, gentle humor is often used to highlight human foibles, adding depth and entertainment to the narrative. In the context of the Champaran episode or Gandhi's life in general, gentle humor can be found in various instances. Here are a few examples:

1. Description of Gandhi's Appearance: The author may use gentle humor to describe Gandhi's appearance or habits in a lighthearted manner. For instance, describing Gandhi's simple attire and austere lifestyle, such as his preference for homemade clothes or his habit of spinning yarn, can evoke a sense of gentle amusement while also emphasizing his commitment to simplicity and self-sufficiency.

2. Interactions with Villagers: Gandhi's interactions with villagers, especially those who are unfamiliar with his ideas or methods, can provide opportunities for gentle humor. For example, the author might depict humorous misunderstandings or misinterpretations of Gandhi's teachings or actions by villagers, highlighting the contrast between urban and rural perspectives.

3. Satirical Commentary on Social Customs: The author may use gentle humor to offer satirical commentary on social customs or norms prevalent during Gandhi's time. This can include humorous observations on topics such as etiquette, cultural practices, or social hierarchies, revealing the absurdity or contradictions inherent in certain societal conventions.

4. Dialogue between Characters: Dialogue between characters, particularly between Gandhi and others with differing viewpoints or personalities, can be infused with gentle humor. This can involve witty banter, playful exchanges, or humorous misunderstandings that reflect the complexities of human relationships and communication.

5. Self-Deprecating Humor: Gandhi himself was known to possess a keen sense of self-awareness and often employed self-deprecating humor. This can manifest in anecdotes or reflections where Gandhi humorously acknowledges his own shortcomings or mistakes, demonstrating humility and a willingness to laugh at oneself.

By incorporating gentle humor into the narrative, the author can effectively engage the reader and provide moments of levity amidst more serious themes. This not only makes the piece more interesting and entertaining but also humanizes the characters and allows for a deeper exploration of their personalities and motivations.
