Deep sleep
अतः सुषुप्त्यवस्था का? अहं किमपि न जानामि सुखेन मया निद्राऽनुभूयत इति सुषुप्त्यवस्था । कारणशरीराभिमानी आत्मा प्राज्ञ इत्युच्यते ।
ataḥ suṣuptyavasthā kā? ahaṃ kimapi na jānāmi sukhena mayā nidrā'nubhūyata iti suṣuptyavasthā | kāraṇaśarīrābhimānī ātmā prājña ityucyate |
Then what is the deep-sleep state? 'I knew nothing at all; I slept in ease.' That recollection is the deep-sleep state. The Self, taking the causal body as itself, is called prājña.
