ॐ गुरुपरमात्मने नमः
4.98.2
न चिदाभासः आत्मा
यथा दीपस्य प्रकाशः, दीपावच्छिन्नाकाशश्च अभिन्नः एव, तथापि भिन्नः एव। यथा तप्तायःपिण्डस्य अग्नेः लोहस्य च अभिन्नतां प्रतीतायां तौ भिन्नौ एव। एवमेव अन्तःकरणस्य आत्मनः अभिन्नतायां प्रतीत्यां सत्यां ते भिन्ने एव। यतः सुषुप्तौ अन्तःकरणं लीयते, आत्मा तु अज्ञानस्य साक्षी भूत्वा प्रतीयते।
The cidābhāsa is not ātmā
The light of a lamp, and space enclosed by the light is non-different, but is also different. The fire and iron ball in a heated ball of iron are not different, but appear different.
In the same way, though the antaḥkaraṇa and ātmā appear non-different, they are different. After all, the antaḥkaraṇa does not function in suṣupti, but the ātmā which is the sākṣī for the ignorance [in that state] is known.
