Who is speaking and story frame
सुप्तिमूर्च्छोपतापेषु प्राणायनविघातत: ।
नेहतेऽहमिति ज्ञानं मृत्युप्रज्वारयोरपि ॥ ७१ ॥
supti-mūrcchopatāpeṣu
prāṇāyana-vighātataḥ
nehate ’ham iti jñānaṁ
mṛtyu-prajvārayor api
When the living entity is in deep sleep, when he faints, when there is some great shock on account of severe loss, at the time of death, or when the body temperature is very high, the movement of the life air is arrested. At that time the living entity loses knowledge of identifying the body with the self.
