śrī bhagavān uvāca—the Supreme Personality of Godhead said; imam—this; vivasvate—unto the sun-god; yogam—the science of one’s relationship to the Supreme; proktavān—instructed; aham—I; avyayam—imperishable; vivasvān—Vivasvān (the sun-god’s name); manave—unto the father of mankind (of the name Vaivasvata); prāha—told; manuḥ—the father of mankind; ikṣvākave—unto King Ikṣvāku; abravīt—said.

The Blessed Lord said: I instructed this imperishable science of yoga to the sun-god, Vivasvān, and Vivasvān instructed it to Manu, the father of mankind, and Manu in turn instructed it to Ikṣvāku.

sa kaleneha mahata

yogo nastah parantapa

evam—thus; paramparā—disciplic succession; prāptam—received; imam—this science; rājarṣayaḥ—the saintly kings; viduḥ—understood; saḥ—that knowledge; kālena—in the course of time; iha—in this world; mahatā—by great; yogaḥ—the science of one’s relationship with the Supreme; naṣṭaḥ—scattered; parantapa—O Arjuna, subduer of the enemies.

This supreme science was thus received through the chain of disciplic succession, and the saintly kings understood it in that way. But in course of time the succession was broken, and therefore the science as it is appears to be lost.
