Fiery World I, 513. A neophyte asked a Rishi who spoke to him about Agni, “If I constantly repeat the word Agni, will I have any benefit from it?” The Rishi answered, “Of course. You have been so far removed from this concept that even through sound your nature will cling to the great foundation of Existence.” In the same way We repeat about the various qualities and analogies of the great Agni. May the people accept this sound in the Chalice! Let them be so saturated with its reverberations that they accept it as inalienable to them. If, during the transition between existences, they even pronounce “Agni,” it will be of help to them, because they will not be hostile toward Fire. The Subtle World will help to sensitize the understanding of the higher principles, but they cannot be approached with hostility and denial. The aim of the first book about the Fiery World is to affirm and accustom people to an understanding of Agni. Let them see how diversely Fire has been understood, from ancient times up to the present contemporary understanding. May the sparks of these fires of the heart recall to mind many mysterious manifestations and the recounting of legends by the old people. One must absorb into one’s consciousness an attractive constructive image. One should admit it as one’s own possession which will lead to the heights. Therefore, even the repetition of sound, Agni, is useful.
Fiery World I, 516. Some people must memorize useful counsels, whereas others know the fundamentals of life in their hearts; both kinds need a Teacher. The first must learn, but the latter should affirm themselves. Some understand the best means for human relations from their earliest years, whereas others must pass through a tiresome schooling in order to avoid destructive actions. Both need the Teaching as a reminder of the conditions of existence. It is astonishing to what a degree some remember instances from their past lives, whereas others have completely lost all memories of their former accumulations. A karmic cause does not completely explain such a marked difference in the understanding of life. Truly, the deciding factor in such understanding lies not in the circumstances of former lives, but in the acceptance of Agni. People call such wisdom a talent, but it is no special talent to keep Agni alight. Only the kindling of the centers produces uninterrupted vigilance of consciousness. Even a partial manifestation of Agni already preserves the accumulations inviolate. Agni is no violator, but our friend. It must be explained that the ascent of the spirit is indeed a manifestation of Agni.
12.11.1943 H.Roerich to R.Rents. “[…] So, Agni, or Fire, is inherent in every creature and creation. Agni is manifested in all things, Agni is inseparable from life, there is no life without Agni. Fiery or Agni energy, in its basic meaning is fundamental, primordial energy, which turns into psyhic energy when passing through or combining with an organised focus or organism.
That is, Fire is the foundation, but the psychic energy is already a combination of fire with thought. Namely, fiery energy needs to be combined with thought, because then fire reveals all the qualities of psychic energy. Thus, energy of thought is one of the highest manifestations or qualities of psychic energy.”
