Boris De Zirkoff was the grand-nephew of H. P. Blavatsky. For many decades, Boris De Zirkoff engaged with utter dedication editing the collected writings of Helena Petrovna Blavatsky. Asked how he came to undertake that project, he said,
When I came to Point Loma in 1924 and began to read some of the old theosophical publications like The Theosophist and Lucifer it became obvious to me that H. P. B. had written a great deal more than The Secret Doctrine and Isis Unveiled. Nothing had been done about it. Her writings were, to my understanding, voluminous but inaccessible except to those who could consult old publications which, obviously hardly anybody could do except those in large centres. So I felt that there was a very real and urgent need to have her collected writings put together in uniform editions. In 1924 or in 1925, I began doing just that, quietly, without saying very much to anybody. A couple of years later, I told Katherine Tingley, who was the Leader in Point Loma, that I was doing so and from then on it became an official undertaking.
The definitive edition of HPB's writings resulted in 14 volumes of articles, notes and Blavatsky's diaries. Each volume has biographical details on the main people mentioned as well as a historical survey of the period and an index.
