Haridas Chaudhuri

He was a correspondent with Sri Aurobindo and the founder of the California Institute of Integral Studies (CIIS).

[1] He studied at the Scottish Church College and later at the University of Calcutta from where he earned his doctorate in Indian philosophy.

In 1951, Chaudhuri was invited by Frederic Spiegelberg of Stanford University to join the staff of the newly formed American Academy of Asian Studies in San Francisco, having been recommended for that post by Sri Aurobindo during the final year of Aurobindo's life.

His version of integral psychology has almost nothing in common with that of Ken Wilber, who has written a book of the same name.

[citation needed] Bahman Shirazi of the California Institute of Integral Studies has defined integral psychology as "a psychological system concerned with exploring and understanding the totality of the human phenomenon....(which) at its breadth, covers the entire body-mind-psyche-spirit spectrum, while at its depth...encompasses the previously explored unconscious and the conscious dimensions of the psyche, as well as the supra-conscious dimension traditionally excluded from psychological inquiry".
