Śrīmad-Bhāgavatam · Text 11.22.51
Who is speaking and story frame
प्रकृतेरेवमात्मानमविविच्याबुध: पुमान् ।
तत्त्वेन स्पर्शसम्मूढ: संसारं प्रतिपद्यते ॥ ५१ ॥
prakṛter evam ātmānam
avivicyābudhaḥ pumān
tattvena sparśa-sammūḍhaḥ
saṁsāraṁ pratipadyate
An unintelligent man, failing to distinguish himself from material nature, thinks nature to be real. By contact with it he becomes completely bewildered and enters into the cycle of material existence.
