Śrīmad-Bhāgavatam · Text 1.3.37
Who is speaking and story frame
न चास्य कश्चिन्निपुणेन धातु-
रवैति जन्तु: कुमनीष ऊती: ।
नामानि रूपाणि मनोवचोभि:
सन्तन्वतो नटचर्यामिवाज्ञ: ॥ ३७ ॥
na cāsya kaścin nipuṇena dhātur
avaiti jantuḥ kumanīṣa ūtīḥ
nāmāni rūpāṇi mano-vacobhiḥ
santanvato naṭa-caryām ivājñaḥ
The foolish with a poor fund of knowledge cannot know the transcendental nature of the forms, names and activities of the Lord, who is playing like an actor in a drama. Nor can they express such things, neither in their speculations nor in their words.
