The inscription in HPB's presentation copy to Leo Tolstoy of her 1889 translation of the Book of the Golden Precepts, a guide to the spiritual life used in her school, published as The Voice of The Silence, reads:
Графу Льву Николаевичу Толстому “Одному из немногих” от автора Е. Блаватской. Count Lev Nikolayevich Tolstoy / “one of the few”/ the author / E. Blavatsky
It is reproduced in the entry on Blavatsky in the Russian Wikipedia, translated here.
HPB thought highly of Tolstoy, referring to him as a natural Theosophist, “This great writer is a perfect model for all aspirants to true Theosophy,” and translated his writings in her magazine.
