tam abṛṁhitam ālokya
so ’carad duṣkaraṁ tapaḥ
tam—that; abṛṁhitam—not increasing; ālokya—seeing; prajā-sargam—the creation of the living entities; prajāpatiḥ—Dakṣa, the generator of living entities; vindhya-pādān—the mountains near the Vindhya mountain range; upavrajya—going to; saḥ—he; acarat—executed; duṣkaram—very difficult; tapaḥ—austerities.
But when Prajāpati Dakṣa saw that he was not properly generating all kinds of living entities, he approached a mountain near the Vindhya mountain range, and there he executed very difficult austerities.
