In this work I have essayed to present to the reader the essence of Mahatma Gandhiji’s philosophy of life in the form of a Rosary of 366 “Pearls of Thought” – one “Pearl” for each day of the year, including the leap year – all gleaned from his writings and speeches. The “Pearls” have been so arranged as to make the transition from one thought to the next as smooth as possible, thus enabling the reader to make use of the Rosary either for daily contemplation of the given thought or for continuous reading at a stretch.
