Man is a human being and an animal, a civilized man and a savage, an angel and a demon in one. Every human being carries his Angra Mainyu in his heart. Life is a long battle. Man has to fight evil within himself and in the world without. He has to seek the enemy, shake his fist at him, wage war with him, bravely face his attacks, intrepidly risk his all and subdue the evil in his nature.
Life is neither all gaiety, nor all gloom.
The world is not heaven, nor is it hell. The rose has its thorns and prickles. The fairest of flowers has its canker. The orchard produces sweet and sour, wholesome and poisonous fruit. Splendor and squalor, fragrance and filth, beauty and ugliness, sumptuousness and want, health and sickness, happiness and misery, exist side by side in this world of contrasts.
