12 Apply your heart to instruction
and your ears to words of knowledge.
The heart languishes without instruction, as does the mind without knowledge. This is key to the cultivation of wisdom, which does not come naturally but through careful exposure to the right things. The plant which lacks sunlight may be exposed to many other things, just as the heart without instruction and the mind without knowledge, but none can flourish in such a state. What sort of fruit do you hope to cultivate in your life? Let this determine what you expose yourself to.
