śāstrera nā jāne marma adhyāpanā kare
śāstrera nā jāne marma adhyāpanā kare |
gardabhera prāya yena śāstra vahi mare ||
paḍhiyā śuniñā loka gela chārakhāre |
kṛṣṇa mahāmahotsave vañcila tāhāre ||
(Caitanya-bhāgavata: 2.1.158–159)
“One who does not know the purport of the śāstra yet teaches [śāstra to others only] bears the śāstra and languishes like a donkey [i.e., as a beast of burden suffers from bearing a load without ever experiencing the benefit the goods it carries can provide, such as the fragrance that can be released from a load of sandalwood it carries, so someone who teaches the śāstra but does not understand its purport only undergoes the trouble of studying and teaching without experiencing the benefit that the knowledge meant to be conveyed by the śāstra can produce, that is, the superlative joy of Kṛṣṇa-bhakti].[Even] After hearing and studying [the śāstra], the person [who teaches the śāstra without understanding its purport] is laid to waste. Kṛṣṇa deprives them of the ultimate grand festival [i.e., the superlative joy of discussion, realization, and so forth of himself].”
