且前有金玉。後有兕虎。人心捨而走。不敢取之何也。以其先命而後利也（兕音寺。似牛一角。身重千斤。以虎為食。乃傷人之惡獸也。且喻前面雖有金銀珠玉。其後或有兕虎。故人必定棄拾而走。不敢取前面金玉者。何為然也。蓋先愛性命。然後可以樂財利也）。

Moreover, suppose ahead there is gold and jade, while behind there is a rhinoceros or a tiger. Why would the human mind abandon them and flee, not daring to take them? Because one puts life first and profit second. (The rhinoceros is pronounced si; it resembles an ox with a single horn, weighs a thousand catties, preys on tigers, and is a ferocious beast that harms humans. Furthermore, it serves as an analogy: even if gold, silver, pearls, and jade lie before one, if behind there may be a rhinoceros or tiger, one is sure to abandon them and flee, not daring to take the gold and jade ahead. Why is this so? Because one cherishes life first, and only after that can one take pleasure in wealth and profit.)
