Agni Yoga (Living Ethics) is a philosophical and ethical doctrine that affects all aspects of life - from cosmological issues to the everyday life of an ordinary person, brought into the world in the first half of the 20th century by the Roerich spouses - Roerich, Helena Ivanovna and Roerich, Nicholas Konstantinovich.

The Books of Living Ethics arose from selected conversations of the Himalayan Mahatma M. with Helena Ivanovna and Nicholas Konstantinovich Roerich. E. I. Roerich wrote down all the conversations in her diaries-manuscripts. Based on these records, books have been published.
