「馳騁四方以求衣食」者，第三、子漸還鄉譬。衣食者人天樂也。四方者四生也。又四方者除地獄、畜生餘四趣也。無處不求為馳騁也。

'Galloping in all four directions seeking food and clothing' is the third, the parable of the son gradually returning to his native land. Food and clothing are the pleasures of humans and gods. The four directions are the four forms of birth. Furthermore, the four directions are the other four realms, excluding hell and animals. Seeking everywhere is 'galloping'.
