The Lotus Sūtra 2.18

2.18

「舍利弗！若國邑聚落有大長者，其年衰邁，財富無量，多有田宅及諸僮僕。其家廣大，唯有一門，多諸人眾，一百、二百乃至五百人，止住其中。堂閣朽故，牆壁隤落，柱根腐敗，梁棟傾危，周匝俱時歘然火起，焚燒舍宅。長者諸子，若十、二十，或至三十，在此宅中。長者見是大火從四面起，即大驚怖，而作是念：『我雖能於此所燒之門安隱得出，而諸子等，於火宅內樂著嬉戲，不覺不知、不驚不怖，火來逼身，苦痛切己，心不厭患，無求出意。』

"Śāriputra, suppose in a country, city, or village there was a great elder, advanced in years, of immeasurable wealth, with many fields, houses, and servants. His house was vast, having only a single gate, and many people—a hundred, two hundred, or even five hundred—dwelt within it. Its halls and pavilions were old and decaying, the walls collapsing, the bases of the pillars rotting, the beams and rafters tilting and precarious, when all around at once a fire suddenly broke out, burning the house. The elder's sons, ten, twenty, or perhaps thirty, were inside this house. Seeing this great fire arising on all four sides, the elder was greatly terrified, and thought: 'Although I was able to escape safely through this burning gate, my sons are happily absorbed in playing games inside the burning house, unaware and unknowing, neither frightened nor terrified. The fire comes pressing upon their bodies, and severe pain cuts into them, yet their minds feel no distress, and they have no intention of seeking an escape.'
