The legacy of Teacher Peter Denov (Beinsa Duno) begins to gradually open up to the reader. Of the thousands of conversations and lectures he left, only a few have been published in our country. This publication is a collection built on thematically selected excerpts from his immense Word. All together they form a single and harmonious whole - a unique material that gives a vivid idea of the Teachings of the White Brotherhood, brought to Bulgarian soil by the Teacher in the first half of the 20th century. The book was first published in 1939 in Sofia, later republished in 1947 and 1992. In Russian, its first publication was published in 1994 by the Siberian publishing house "Compass-Papyrus" (Krasnoyarsk). In 1997 it was published in Lithuanian. This Russian edition is the second. The translation has been newly edited and some clarifications have been made. The publisher hopes that this book will serve the reader as a reliable guide in the world of ideas of the new Teaching, with which he will become widely acquainted in the future.
