पुरा देवयुगे तात देवेन्द्रेषु महात्मसु
purā devayuge tāta devendreṣu mahātmasu
Bhīṣma said: “In ancient times, dear one, in the divine age—when the great-souled gods and Indra-like lords were present…”
भीष्म उवाच
The verse functions as a traditional frame for instruction: Bhīṣma introduces an ancient divine-era precedent, implying that dharma is best understood through time-tested exemplars set by great beings.
Bhīṣma begins a recollection (“formerly, in the age of the gods…”) addressed affectionately to his listener, setting up a story about exalted deities/Indra-like rulers as the background for the moral teaching that follows.
