Chapter 4, Text 1
imaṁ vivasvate yogaṁ
proktavān aham avyayam
vivasvān manave prāha
manur ikṣvākave ‘bravīt
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.
Herein we find the history of the Bhagavad-gītā traced from a remote time when it was delivered to the royal order, the kings of all planets. This science is especially meant for the protection of the inhabitants and therefore the royal order should understand it in order to be able to rule the citizens and protect them from the material bondage to lust. Human life is meant for cultivation of spiritual knowledge, in eternal relationship with the Supreme Personality of Godhead, and the executive heads of all states and all planets are obliged to impart this lesson to the citizens by education, culture and devotion. In other words, the executive heads of all states are intended to spread the science of Kṛṣṇa consciousness so that the people may take advantage of this great science and pursue a successful path, utilizing the opportunity of the human form of life.
