Sri Aurobindo (Bengali: শ্রী অরবিন্দ Sri Ôrobindo) (15 August 1872 – 5 December 1950), born Aurobindo Ghosh or Ghose (Bengali: অরবিন্দ ঘোষ Ôrobindo Ghosh), was an Indian nationalist, freedom fighter, philosopher, yogi, guru, and poet. He joined the Indian movement for freedom from British rule and for a duration became one of its most important leaders, before developing his own vision of human progress and spiritual evolution.

The central theme of Aurobindo's vision was the evolution of human life into life divine. He wrote: "Man is a transitional being. He is not final. The step from man to superman is the next approaching achievement in the earth evolution. It is inevitable because it is at once the intention of the inner spirit and the logic of nature's process."

Aurobindo's writings synthesized Eastern and Western philosophy, religion, literature, and psychology. Aurobindo was the first Indian to create a major literary corpus in English.His works include philosophy; poetry; translations of and commentaries on the Vedas, Upanishads, and the Gita; plays; literary, social, political, and historical criticism; devotional works; spiritual journals and three volumes of letters. His principal philosophical writings are The Life Divine and The Synthesis of Yoga, while his principal poetic work is Savitri: A Legend and a Symbol.

Peter Heehs is an American historian living in Pondicherry, India who writes on modern Indian history, Indian spirituality and religion. Much of his work focuses on the Indian political and spiritual leader Sri Aurobindo. His publications include nine books and more than fifty articles in journals and magazines.

Peter Heehs was born and educated in the United States but has lived in India since 1971. He has worked as a researcher and editor at the Sri Aurobindo Ashram Archives since its founding, and has contributed to the editing of the Sri Aurobindo Birth Centenary Library and The Complete Works of Sri Aurobindo.

As a historian of modern India, Heehs has written on the swadeshi period of the Indian independence movement and on the early phase of the Indian revolutionary movement. His 1992 study The Bomb in Bengal highlighted the importance of the Maniktala secret society, which was a predecessor of the Jugantar Group. In this book and other publications, Heehs made it clear that the Indian freedom struggle had a violent as well as a non-violent side, and that the violent revolutionaries helped prepare the country psychologically for the later mass movements led by Mahatma Gandhi. In the second edition of The Bomb in Bengal (2004), Heehs distinguished the aims and methods of early Indian revolutionaries from those of later terrorists in India and elsewhere.
