In the Srimad-Bhagavatam 7.6.3, Srila Prabhupada writes in the Purport,
“Our only business in the human form of life should be to revive our relationship with the Supreme Personality of Godhead and thus become qualified to return home, back to Godhead. Material happiness and distress come as soon as we accept a material body, regardless of what form. We cannot avoid such happiness and distress under any circumstances. The best use of human life, therefore, lies in reviving our relationship with the Supreme Lord, Viṣṇu.”
