413 Arhat Lokaprabhāsa (Bright World)
The rivers, lakes, and seas in nature have their naturally formed boundaries; while knowledge and wisdom are vast and endless. Delving into the ocean of wisdom, exploring its breadth and depth, can bring supreme joy, making one sigh that life is limited, but the sea of learning is boundless.
For those who receive this verse, one must be a diligent student and experience the joy of reading. But one should know that life is limited, and knowledge is boundless. Learning is for practical use; useless learning is like a dragon-slslaying skill, no matter how much, what good is it? Therefore, those who study diligently until old age are merely old scholars; those who learn and practice can become renowned people in the world. Where to go, please ponder deeply.
