"How powerful the spirit of man, while his body is so weak!"

"The human body is in reality very weak; there is no physical body more delicately constituted. One mosquito will distress it; the smallest quantity of poison will destroy it; if respiration ceases for a moment, it will die. What instrument could be weaker and more delicate? A blade of grass severed from the root may live an hour, whereas a human body deprived of its forces may die in one minute. But in the proportion that the human body is weak, the spirit of man is strong. It can control natural phenomena; it is a supernatural power which transcends all contingent beings. It has immortal life, which nothing can destroy or pervert. If all the kingdoms of life arise against the immortal spirit of man and seek its destruction, this immortal spirit, singly and alone, can withstand their attacks in fearless firmness and resolution because it is indestructible and empowered with supreme natural virtues. For this reason we say that the spirit of man can penetrate and discover the realities of all things, can solve the secrets and mysteries of all created objects. While living upon the earth, it discovers the stars and their satellites; it travels underground, finds the metals in their hidden depths and unlocks the secrets of geological ages. It can cross the abysses of interstellar space and discover the motion of inconceivably distant suns. How wonderful it is! It can attain to the Kingdom of God. It can penetrate the mysteries of the divine Kingdom and attain to everlasting life. It receives illumination from the light of God and reflects it to the whole universe. How wonderful it is! How powerful the spirit of man, while his body is so weak! If the susceptibilities of the spirit control him, there is no created being more heroic, more undaunted than man; but if physical forces dominate, you cannot find a more cowardly or fearful object because the body is so weak and incapable. Therefore, it is divinely intended that the spiritual susceptibilities of man should gain precedence and overrule his physical forces. In this way he becomes fitted to dominate the human world by his nobility and stand forth fearless and free, endowed with the attributes of eternal life."
