The books "Agni Yoga" and "The Fiery World", of which this collection consists, give an idea of the essence and meaning of the teaching of the Living Ethics - perhaps the most famous esoteric work of the 20th century. Its creators are Nicholas and Helena Roerich. The culture of the new society, which is based on the cosmic Law, the description of the principles of transformation of the energies of human feelings and thoughts, and the moral instructions for future generations arising from this - not a single concept of the new world, which should be formed after the coming purification by Fire, has been so broadly and in detail set forth. In total, the corpus of Agni Yoga consists of 14 books, which were published in Russian in the 20-30s. in Riga and Paris. At present, they have been translated into many world languages, and all over the world there are still various societies of followers of the Living Ethics. This is probably the best proof that at one time the Roerichs were not only at the forefront of esoteric philosophy, but also in many ways ahead of their time, leaving a huge reserve for the future of other generations.
