Read the Sanskrit as a connected thought built from sahasra (one thousand), viduḥ (know), and janāḥ (people). Ask what changes between the first and last term, and how that movement contributes to remembrance that shapes one's destination. State the connection in your own words, then check it against Bhagavad-gita 8.17.
