In the many years following the passing of HPB, thousands of "changes and corrections" had been made to the original writings of HPB and Mr. Judge. Such deletions and additions were the product of prominent "post-HPB" Theosophists. The ULT makes the effort to preserve and to "Spread Broadcast the original teachings of Theosophy as found in the writings of H.P. Blavatsky and William Q. Judge." To that end, the texts regarded as "straight line Theosophical Literature" by the ULT are generally those which are reproduced from the original plates, or are photographic reproductions of originals. After Crosbie's death the movement gained momentum under the leadership of B.P. Wadia (1881–1958). Sri Raghavan Iyer was a prominent member of the movement until his death in 1995.
