Aleksandr Solzhenitsyn said this quote
“ Our life consists not in the pursuit of material success but in the quest for worthy spiritual growth. Our entire earthly existence is but a transitional stage in the movement toward something higher, and we must not stumble and fall, nor must we linger fruitlessly on one rung of the ladder. Material laws alone do not explain our life or give it direction. The laws of physics and physiology will never reveal the indisputable manner in which the Creator constantly, day in and day out, participates in the life of each of us, unfailingly granting us the energy of existence; when this assistance leaves us, we die. And in the life of our entire planet, the Divine Spirit surely moves with no less force: this we must grasp in our dark and terrible hour. ”
