Nerushimoye, the book by Prof. Nicholas Roerich, was published in Russian in 1936 in Riga by Uguns — the publishing house.
The preface to that book is significant enough to repeat in this English edition:
"In the present eleventh volume of his works, called by the author Nerushimoye ("The Invincible"), N.K. Roerich, indefatigable and widely recognized as a cultural leader of humanity, remains faithful to his task and to the goal that he sets before himself. He stands invincibly on watch over culture; invincibly and yet steadfastly he molds the steps of the consciousness of the new man; invincibly and strongly he lays the stones into a beneficent, true, spiritual culture as the basis of the structure of new life; invincibly and fearlessly he battles with ignorance, superstition, and prejudices and, in spite of the attacks of numerous adversaries, he continues to carry out unalterably the ideas of a peaceful, cultural structure of life.
"Vigilantly watching all that happens in life upon our planet, the author in this work also reacts constantly, like a sensitive barometer, to all events and manifestations of life, positive as well as negative. Any and all, the great and also the smallest manifestations of life find a living response in his many faceted heart, and a just, impartial evaluation by his all-embracing mind. There is no realm of knowledge or sides and issues of life that would be unattainable to his understanding and are not widely examined in his numerous letters and articles.
"Standing on guard over culture, Roerich dedicated his entire life to the battle with ignorance, for culture is to him the hearth of Light, a constant saturation and transmutation of consciousness by the light of higher knowledge and active love".
"In this incessant drive for the annihilation of darkness is disclosed the astonishing quality of his spirit, which ever delighted his friends — to approach everything without negation and intolerance, to observe in each cultural endeavor something positive, and to incorporate this actuality into the common evolutionary treasury of the world. This is precisely that high ideal of cultural constructiveness which N.K. Roerich brought into being in the many organizations and societies in which he realized a League of Culture — precisely that affirmatively synthesized undertaking in which is revealed that all-creative spirit of unity, cooperation, and service, and where are put together the bases of the best future for humanity."
There is little we can add in 1974 to this just evaluation. Let The Invincible summon forth and exalt the best qualities of the human spirit.
