Terence James Stannus Gray was born in Felixstowe, Suffolk, England on 14 September 1895, the son of Harold Stannus Gray and a member of a well-established Anglo-Irish family. He was raised on an estate in the Gog Magog Hills outside Cambridge, England. He received a thorough education at Ascham St Vincent's School, Eastbourne, Eton and Oxford University. Early in life he pursued an interest in Egyptology which culminated in the publication of two books on ancient Egyptian history and culture in 1923.

In the later part of his life he lived with his second wife, the Georgian princess Natalie Margaret Imeretinsky, in Monaco. He had previously been married to a Russian noblewoman, Rimsky-Korsakov.^[2]

Gray maintained his family's racehorses in England and Ireland and in 1957 his horse Zarathustra won the Ascot Gold Cup, ridden by jockey Lester Piggott in the first of his eleven wins of that race.

In the 1920s and 1930s, Gray worked as a theorist, theatrical producer, creator of radical "dance-dramas", publisher of several related magazines and author of two related books. His cousin was Ninette de Valois, founder of the Royal Ballet.^[1]

In 1926, Gray, with no previous practical theatrical experience, opened the Cambridge Festival Theatre as an experimental playhouse.^[1] He acquired the old Theatre Royal in the Cambridge suburb of Barnwell, and substantially rebuilt it.^[1] The opening production was Aeschylus' The Orestia, with de Valois as choreographer, and he continued to produce non-naturalistic productions, emphasising movement over speech.^[1] Doria Paston worked as an actress and set designer with Gray for seven years.^[3] Critics were divided, with some praising his achievements, and others saying he sacrificed text and acting to clever trickery. Gray delighted in upsetting audiences but, despite controversy, audiences filled the theatre.^[1]

Many of Gray's collaborators left the project over his inability to compromise.^[1] By 1933, he had abandoned theatre for good.^[4]

After he left his theatrical career, his thoughts turned towards philosophy and metaphysics. This led to a period of travel throughout Asia, including time spent at Ramana Maharshi's ashram in Tiruvannamalai, India.^{[citation needed]} Between the years 1958 and 1974, eight books and articles in various periodicals appeared under the pseudonym "Wei Wu Wei" (Wu wei, a Taoist term which translates as "action that is non-action").^[5] His identity as the author was not revealed at the time of publication for reasons he outlined in the Preface to the first book, Fingers Pointing Towards the Moon (Routledge and Kegan Paul, 1958).

The next 16 years saw the appearance of seven subsequent books, including his final work under the further pseudonym "O.O.O." in 1974. Wei Wu Wei influenced among others, the British mathematician and author G. Spencer-Brown, Galen Sharp, and Ramesh Balsekar.^{[citation needed]} Wei Wu Wei is discussed in some detail in the book Taoism for Dummies (John Wiley and Sons Canada, 2013). A biography was published in 2004.^[5]
