The servants at Rajendra Prasad’s house did not allow Gandhi to draw water from the well because they mistook him for an untouchable, as mentioned in the chapter Indigo from Class 12th. Gandhi arrived at the house dressed simply, resembling a poor peasant rather than a prominent leader, which led the servants to assume he belonged to a lower caste. Concerned that he might pollute the well, they restricted his access to water. This incident reflects the deep-rooted caste prejudices prevalent in society at the time, which Gandhi later worked to eradicate through his advocacy for equality and social reform.
