Indra Sen (13 May 1903 – 14 March 1994) was a devotee of Sri Aurobindo and The Mother, psychologist, author, and educator, and the founder of Integral psychology as an academic discipline.
He also attended the lectures of Martin Heidegger and taught Indian Philosophy and Sanskrit at the University of Koenigsberg.
In following years, through lectures, published writings, and personal contacts, he presented Sri Aurobindo's work to academia and universities, where it became well known for the first time.
[4] His papers, which were sent to Sri Aurobindo and later The Mother before publication, were presented at scientific congresses or published in Ashram journals.
One was at Jwalapur, near Haridwar, and the other two in the Kumaon Hills – "Mountain Paradise", an orchard, and "Tapogiri", a place for sadhana (spiritual practice).
