A religious studies scholar
Alvin Kuhn wrote in his thesis that
The Canadian Theosophist, a magazine published at
Toronto, announced a series of articles in which "parallel passages from the writings of Mrs. Blavatsky and the
Mahatma Letters on one side, and from the books of Mrs. Besant and Mr. Leadbeater, on the other (
Man: whence, how and whither included), gave specific evidence bearing on the claims of perversion of the original theories by those whom they call
Neo-Theosophists." John Prentice in an article
Clairvoyant Research criticized the book of the authors. He proclaimed that the material for the
Peruvian lives in
Man: whence, how and whither (Ch. XI) had been lifted out of Garcilaso de la Vega's
Royal Commentaries on the Yuccas of Peru (written in 1609 and published in English translation in 1638, 1869 and 1871). Joseph Fussell wrote about "abnormal and preposterous claims" published by Besant and Leadbeater.
Helena Roerich stated that Leadbeater's books are a mix of "false and ugly" statements and some fragments of truth: one of the
Great Masters supposedly called the book
Man: Whence, How and Whither as "a work which devoid of knowledge, honesty and beauty." She wrote: "The book by Besant and Leadbeater is particularly awful, therein is described the lives supposedly the Great Masters and some their pupils, namely: Besant, Leadbeater... I've never seen anything equal to this tasteless blasphemy and falsehood." Professor
Olav Hammer stated that Leadbeater's claims about past lives "were increasingly used to buttress power struggles." He wrote, "Those who supported the controversial Leadbeater were recorded as having had important roles in the past, while his opponents were depicted as villains." In his thesis Hammer wrote: "How can Leadbeater's readers know that his clairvoyant results really are 'records' and 'information', rather than delusions or deliberate fabrications? His response is feeble, 'there is no assurance. The investigators themselves are certain of the difference between observation and imagination'."
Alice Bailey stated that the book published at Adyar by Besant and Leadbeater was "psychic in his implications and impossible of verification". In her
Unfinished Autobiography she wrote that it proved to her the "untrustworthiness" of Leadbeater's writings: "Books were being published at Adyar by Mr. Leadbeater that were psychic in their implications and impossible of verification, carrying a strong note of astralism. One of his major works,
Man: Whence, How and Whither, was a book that proved to me the basic untrustworthiness of what he wrote. It is a book that outlines the future and the work of the Hierarchy of the future, and the curious and arresting thing to me was that the majority of the people slated to hold high office in the Hierarchy and in the future coming civilisation were all Mr. Leadbeater's personal friends. I knew some of these people—worthy, kind, and mediocre, none of them intellectual giants and most of them completely unimportant." == Publications ==
