CC Madhya 6.134

mukhyārtha chāḍiyā kara gauṇārtha kalpanā
‘abhidhā’-vṛtti chāḍi’ kara śabdera lakṣaṇā
Word for word: 
mukhya-artha — direct meaning; chāḍiyā — giving up; kara — you do; gauṇa-artha — indirect meaning; kalpanā — imagining; abhidhā-vṛtti — the meaning that is understood immediately; chāḍi’ — giving up; kara — you do; śabdera — of the words; lakṣaṇā — interpretation.
Translation: 
“For each sūtra the direct meaning must be accepted without interpretation. However, you simply abandon the direct meaning and proceed with your imaginative interpretation.
