Śrīmad-Bhāgavatam · Text 11.28.3
Who is speaking and story frame
तैजसे निद्रयापन्ने पिण्डस्थो नष्टचेतन: ।
मायां प्राप्नोति मृत्युं वा तद्वन्नानार्थदृक् पुमान् ॥ ३ ॥
taijase nidrayāpanne
piṇḍa-stho naṣṭa-cetanaḥ
māyāṁ prāpnoti mṛtyuṁ vā
tadvan nānārtha-dṛk pumān
Just as the embodied spirit soul loses external consciousness when his senses are overcome by the illusion of dreaming or the deathlike state of deep sleep, so a person experiencing material duality must encounter illusion and death.
Read the purport on Vedabase.ioFrom Canto 10, chapter 14 onward, the translation and purports were completed by Śrīla Prabhupāda's disciples after his departure, and published by the Bhaktivedanta Book Trust.
