Explanation: If a wise person were to associate with a wise person, even for a moment, he will quickly understand the Teaching. This is very much like the tongue being able to discern the subtle flavours of soup. This stanza could be further appreciated when you contrast it with the previous one. In the previous one the image used is the soup. Though it serves tasty food endlessly, it just cannot appreciate how food tastes, very much like a foolish individual being unable to appreciate the teaching even when he keeps company with the wise. An intelligent man, even though he is associated with a wise man only for a moment, quickly understands the Dhamma, just as the tongue knows the taste of soup.
