An Agni Yoga Compilation
The element of Fire, the most all-pervading, the most creative, the most life-bearing, is least observed and esteemed. The human consciousness concerns itself with a multitude of empty and insignificant considerations, but the most wonderful of all escapes it. People quarrel over a price in the bazaar, but they have no desire to stretch forth their hands to the treasure.  Much that has been told about the heart must also be applied to the Fiery World, but with particular acuteness. The impetus of Fire is as strong as the structure of a crystal. Not by accident have globes and crystal spheres been employed by clairvoyants. Live embers are needed for the purification of the consciousness; the rainbow flame affirms the striving of the spirit. A multitude of applications of the work of Fire reveal themselves as the most striking conditions of existence. 

Beginning with the ordinary light formations visible to the open eye, up to the complex fires of the heart, we are led into the realm of the Fiery World. Fiery World I (1933),  paragraph 1 

While observing the fiery signs one may note certain subdivisions of people. Some strive eternally and cannot exist without this uplifting movement—be assured that these belong to the element of fire. Even though they err, they cannot remain inactive. Observe them, and you will invariably discover the flaming force. But do not seek the creative Fire in the inertia of earth, the rolling undulations of water, the gusts of air.

   We do not wish to extol the fiery people unduly, but in truth it must be said that they move the world. One should not forget that these people do not find it easy to be in the midst of all other combinations. What is said about the Fiery Angel with scorched wings is correct. When he rushes to save the world, his phosphorescent wings brush against the rocks of Earth and are scorched, and the Angel is weakened thereby. Thus is disclosed the marked difference between the earthly world and the Fiery.

   The earthly eye, though it be highly sensitive, does not usually assimilate even the subtle manifestations. But, in turn, the Subtle World does not discern the fiery dwellers to whom the flaming heart can lead one. Thus one can understand the veneration for Fire. Human strivings are needed for a natural affinity with the World of Fire. From early years they bear in themselves, as it were, a reflection of the Higher Fire. It is as if these sparks compel them to withdraw from contact with other elements; and those elements do not like these fiery orbs. Yet one cannot traverse the earthly path without contact with Fire, hence it is better to know its essential nature. Fiery World (1933), paragraph 2

   When we speak of the non-scorching fire, we must also not forget the consuming Fire. When the nun moans, “I burn, I burn!” no physician knows how to alleviate it. The physician may even apply cold water, forgetting that oil cannot be submerged in water. Fire can be allayed only by fire—in other words, by the energy of the heart, which flows during so-called magnetism. We treat inflammation with a current; such inflammations may flare up in various centers. But, actually, the chief danger lies close to the heart, the solar plexus and the larynx.  These centers, being the most synthetic, may be exposed to the most unexpected attacks. Whoever has even once experienced the inner fire understands the danger of the conflagration of the centers. He knows what agony is experienced when the fire breaks through. In most cases man is not responsible for this, except perhaps because of irritation. Often the fire bursts out due to extraneous influences, and in the case of a refined state of the organism, from cosmic causes.  Fatigue of the heart actually opens the gates to the enemy. Thus the creative Fire can be transformed into a destructive flame. This should be remembered, for the outbursts develop from small beginnings. It should also be remembered that the use of fiery energy requires care. Great is the evil of needlessly spending the fiery energy of another. An Arhat can never be a vampire—this is a fundamental law of life. Therefore, wise is the law of eternal giving. It may seem that there is nothing in common between sacrifice and Fire; however, flaming sacrifice is mentioned in all Covenants. Fiery World I  (1933), paragraph  5

   A fire is not kindled under water. Achievement is not created in the comfort of a hothouse. In the midst of human burdens let us ask ourselves, “Is this not already an achievement?” In the midst of oppression let us ask, “Is this not forcing us toward the gates of achievement?” In the midst of explosions let us ask, “Have we not sufficient strength within us to ascend by ourselves?” Thus, let us examine every manifestation as to whether it leads to achievement. Thus, let us note everything that moves us toward achievement. Who can foresee precisely what counterblow will put new circumstances into motion? But without a blow, matter will not be brought into motion. These blows upon matter are called “hearthstones of achievement.” Only those who understand the creative substance will realize that what is said is not merely encouragement but the just assertion of a law. One may turn the law into a misfortune, but it is correct to apprehend the usefulness issuing from the foundations of being.Fiery World I  (1933), paragraph  271

   Is not fear of Fire caused by the fact that only its destructive aspect is apparent to the physical eye, whereas its fiery creativeness is not realized in the physical state? One must with especial conviction disclose to people that by reason of their very nature they have a unique path to fire. Can the physician who has an aversion to his patient be a good physician? Or will the warrior whose spirit trembles with fear be victorious? Hence, we shall set before us the highest task, and in this way we shall not notice the steps of transition. Each element primarily precludes fear. To overcome fear momentarily does not mean to eradicate it. We must not be like small children, who are courageous today but may tremble with fear over an empty phantom tomorrow. Nor must we be like the pampered ones who seek daring adventure today but on the morrow will bury themselves in downy pillows. Let us not be under the threat of tomorrow, for of all the elements precisely Agni will not tolerate fear.  We must comprehend Agni not as a destroyer but as a creator! In these two aspects of Agni lies the true touchstone of our nature. Fiery World I   (1933), paragraph 499

   You, my young friends, who have approached art and creation, you should be able to utilize your gifts as a condensation of your forces; for sound and color, thought and rhythm are the foundations of the Universe and of our existence. Sound and color, knowledge and creation are the chalice of Amrita, the Chalice of Immortality!

   Eternal, continuous creation of the universal Life surrounds us, and we, being part of this great creation, should create every moment of our life—create by thought, by word, by action.
My young friends, fill up the treasury of your spirit. Absorb all the sounds, all the colors, all the rhythms from the fathomless sources of space. These finest vibrations, consciously absorbed, will refine your receptivity and your thought.

   The refinement of receptivity will give you the possibility of penetrating into the Sanctuaries of Space, and will open the joyous path of achievement and continuous, endless ascent.
My friends, labor with all the tension of your forces because only by reaching the limit of your tension do new possibilities come to you. The laws are alike in everything. We know that sublime energies are born of the greatest efforts. Therefore, only increased activity and intensified strength will bring the achievement of beauty.

   And I beg you, do not fear difficulties. Display readiness to meet all obstacles, for each obstacle strengthens you and leads you to the future victory. Try to love the difficulties, and say, “Blessed be the obstacles, through them we grow.” Courageously, inspired by striving, realizing the majesty of the endless perfecting of creative life, strive toward the calling Infinity—infinity of lives, infinity of achievements, infinity of knowledge, infinity of construction, infinity of beauty!
 My young friends, hearken to the Call of Creative Infinity! Letters of Helena Roerich, Volume 1 (1929-1938), pp. 4-5
