[455] And furthermore, bhikkhus, the great ocean contains many treasures, treasures of diverse kinds. Therein are these treasures, namely: pearl, gem, beryl, conch, quartz, coral, silver, gold, ruby, and cat's-eye. That the great ocean contains many treasures, treasures of diverse kinds—therein being these treasures, namely: pearl, gem, beryl, conch, quartz, coral, silver, gold, ruby, and cat's-eye—this too, bhikkhus, is the seventh wonderful and marvellous quality in the great ocean, seeing which again and again the asuras delight in the great ocean.
