16.382

又大海中至一分難得者，水鹹難得即陸居一分非福，輪王出世主藏大臣以手攬海，寶隨手出，餘眾生求寶難得，故曰一分難得。

Furthermore, from 'in the great ocean' up to 'one part is difficult to obtain' means: because the water is salty it is difficult to obtain, which is the lack of merit of a part of the land-dwellers. When a wheel-turning king appears in the world, his treasury-master minister scoops the sea with his hand and jewels emerge with his hand; for other sentient beings, seeking jewels is difficult to obtain. Hence it says 'one part is difficult to obtain.'
