This autobiography chronicles Mahatma Gandhi's spiritual and personal journey, starting from his childhood experiments with truth, including early temptations like smoking and stealing, through his time in England studying law and adapting to Western culture, and his transformative years in South Africa fighting racial discrimination. There, he developed satyagraha, or nonviolent resistance, while experimenting with celibacy, simple living, vegetarianism, fasting, and meditation to purify himself and pursue truth. The book, written during his imprisonment, details his ongoing quest to conquer inner passions and achieve self-realization, emphasizing nonviolence and truth as paths to personal and societal change, without covering his full Indian independence struggle.
