Imagine, how wonderful and at the same time how obscure! If we call the heart the spark of fire, then we can see its different aspects as sympathy in the form of heat, as longing in the form of fire, as affection in the form of glowing, as devotion in the form of flame, as passion in the form of smoke that blinds one's eyes. That which gives courage to stand firm in the battlefield, to struggle through life, to endure all that comes, that which strengthens one to have patience, what is it? It is the heart. If the heart fails, one falls; if the heart rises, one rises.
