A horse and a donkey heard that Tang Monk was about to embark on a journey to the West to fetch the sacred scriptures. The donkey, convinced that the trip would be fraught with difficulties, chose to give up. In contrast, the horse immediately followed him. After enduring eighty-one tribulations, the horse successfully retrieved the scriptures. Curious, the donkey asked, "Brother, was the journey really that exhausting?" The horse replied, "While I was on my way to the West, you actually walked no less distance than I did. In fact, you were often blinded and beaten by your owner. To be honest, I chose to go because I was afraid that a life of idleness would be more tiring than the physical hardship of the journey."
