大毘盧遮那成佛經疏 2.51

2.51

第廿二「云何農夫心？謂隨順初廣聞而後求法」者，如學稼者詢問老農：「云何知地良美？云何耕植耘耨？云何候時？云何獲藏？」如是一一知已，方就功力。此心亦爾，先務諮承智者廣聞道品，然後行之。皆宿習使然也。以利智為所對治。如聞諸蘊無常，即知界入緣起等其例皆爾。又如毒箭入體，豈得竢三農月廣問而後拔之耶？

Twenty-second: regarding "What is the farmer mind? It means according with the dharma of first hearing broadly and only later seeking": just as one who learns farming inquires of an old farmer: "How does one know that the land is fertile? How does one plow, sow, and weed? How does one observe the seasons? How does one reap the harvest?" Having understood them one by one in this way, one only then applies effort. This mind is also like this: first devoting oneself to consulting and receiving broad learning in the factors of the Path from the wise, and only then putting them into practice. All are brought about by past habits. Taking sharp wisdom as the antidote: for example, upon hearing that the aggregates are impermanent, one immediately knows that the elements, sense bases, dependent origination, and the like are all analogous. Furthermore, if a poisoned arrow enters the body, how could one wait for the three agricultural months to inquire broadly before pulling it out?
