Māndukya 1.07
atraite ślokā bhavanti ।
Here are these verses:
bahiḥprajño vibhurviśvo hyantaḥprajñastu taijasaḥ। ghanaprajñastathā prājña eka eva tridhā smṛtaḥ ॥7॥
The all-pervading outwardly conscious in the form of 'Viśva', i.e. universal, is indeed also the inwardly conscious, called 'Taijasa' i.e. luminous, and in the form of 'Prājña', i.e. the wise one, carries the heavy and ignorant being; thus remembered to be three-fold.
Bhāshya 1.07
The authenticity of the earlier textual evidence is reinforced by the current textual evidence when they are aligned. In the Garuda Purana, section four, while commenting on this verse, it is stated, Lord Varuna reinforced the ideas by quoting the verses seen by Lord Brahma.
"pramāṇasya pramāṇaṃ ca balavad vidyate mune। brahmadṛṣṭān yato mantrān pramāṇaṃ salileśvaraḥ। atra ślokā bhavantīti cakāraiva pṛthak pṛthak॥"
"O sage, the authenticity of the earlier evidence is reinforced by the current evidence when the two are aligned. Indeed, by quoting the verses as seen by Lord Brahma again and again separately, the Lord of the waters, i.e. Varuna, is reinforcing his message through textual evidence."
iti gāruḍe khaṇḍacatuṣṭaye ॥7॥
- stated thus in the Garuda Purana, section four.
