"O Partha, the word 'Sat' is used in the sense of existence and of goodness; likewise the word 'sat' is used for praiseworthy action."
Interpretation
Shankaracharya. asataḥ sadbhāve yathā avidyamānasya putrasya janmani — when what did not exist comes to be (as at the birth of a son); asadvṛttasya asādhoḥ sadvṛttatā sādhubhāvaḥ — when a person of bad conduct becomes one of good conduct — goodness.
Acharya Ramanuja. sadbhāve vidyamānatāyāṃ sādhubhāve kalyāṇabhāve ca.
Shridhara Swami. Examples from everyday speech: devadattasya putrādikam astīty asminn arthe — "Devadatta has a son" (existence); prāśaste māṅgalike vivāhādikarmaṇi — "sat" for an auspicious act like a wedding.
Madhusudana Saraswati. sad eva somyedam agra āsīt — the "sat" of the Chandogya; and karmavaiguṇyāpanoda — able to remove the deficiencies of an action.
Madhvacharya. sadbhāvaśabdena prajananaṃ sūcitam — "sadbhava" hints at coming into being.
