噢，诸天之主！大地乃一切众生之居处，如今沉没于浩瀚大水之中。请发起努力将其举起；凭你的作为并蒙主（Bhagavān）的慈恩，此事可成。

In this verse, Brahmā states that the earth has sunk into the great cosmic waters and requests the Lord to arrange her upliftment—setting the stage for the Varāha avatāra’s Bhūmi-uddharaṇa (rescue of the earth).
Because the earth, the support for all beings, had become submerged; Brahmā, responsible for secondary creation, appeals to the Supreme Lord—whose divine potency alone can restore cosmic order.
When situations feel “submerged” beyond one’s capacity, this verse models humility and prayerful dependence: do your duty, but seek the Lord’s help as the ultimate shelter and rescuer.
