Dr. Indra Sen = Yudhishthira
Dr. Indra Sen (originally Yudhishthira) (13.05.1903, Jhelum district of Punjab — 14.03.1994), an erudite disciple of Sri Aurobindo and the Mother. He grew up in Delhi, where his family came to live.
He completed the Master’s course in both Philosophy and Psychology from the University of Delhi (Hindu College). Already an M.A., LLB, he had got his doctorate from the University of Freiburg in Germany and taught Psychology and Philosophy at the Hindu College in Delhi.
On 5 December 1928 he married Lilawati, who was a graduate in Education and Child Psychology and was pursuing further studies. Indra Sen and Lilawati had two children – a daughter, Meera, and a son.
In 1939, Indra Sen first travelled to Pondicherry with a friend, Surendranath Jauhar. He returned with Lilawati, then with the children, who were very young. The visits became frequent. After a number of visits, his wife became a devotee of The Mother.
In April 1943, the Mother asked Lilawati to wind up life and work in Delhi and come to live in the Ashram with the children. The Mother named her Violette, so aftewards Lilawati was known as ‘Violette-di’ in the Ashram. In French, it is the name of a flower meaning ‘modesty’. Also the Mother named Meera (Lilawati’s daughter) Aster. Aster Patel was one of the earliest students at the Ashram school.
In 1945 Dr Sen resigned from the University and moved to the Sri Aurobindo Ashram, where his family had already been staying for two years.
In 1981, after settling down at Pondicherry, he took interest in the Ashram and Auroville matters at his own initiative.
