Like many[quantify] of his contemporaries, the boy Daniil had a pronounced literary bent; he began writing poetry and prose in early childhood.

After World War II Andreyev returned to civilian life, but the Soviet authorities arrested him in April 1947, charged him with anti-Soviet propaganda and preparations to assassinate Joseph Stalin,[citation needed] and sentenced him to 25 years of imprisonment.

[1] While incarcerated in Vladimir Central Prison from 1947 to 1957, Andreyev experienced mystic visions and started writing Roza Mira, finishing it after his release.

[3] Almost all works that Andreyev wrote before 1947, were destroyed by Ministry for State Security (MGB) as "anti-Soviet literature", including his novel Wanderers of Night (Russian: Странники ночи) about the spiritual opposition to the Soviet regime and atheism.

His main book, Roza Mira (Russian: Роза Мира, literally "The Rose of the World") contains a detailed description of numerous layers of spiritual reality that surround Earth, of the forthcoming religion called Roza Mira that will emerge and unite all people and states, and of the events of the future advent of Antichrist and his fall.
