Bhagavad-  ળોતા As It Is
[Ch. 4]
TRANSLATION
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 Ikṣṣāku.
प्रारंभिक परिचय
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.
In this millennium, the sun-god is known as Vivasvān, the king of the sun, which is the origin of all planets within the solar system. In the  Brahma-saṁhitā  it is stated:
yac-cakṣur eṣa savitā sakala-grahāṇāṁ rājā samasta-sura-mūrttir aśeṣa-tejāḥ yasyājñayā bhramati sambhṛta-kālacakro govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
“Let me worship,” Lord Brahmā said, “the Supreme Personality of God-head, Govinda [ Kṛṣṇa ], who is the original person and under whose order the sun, which is the king of all planets, is assuming immense power and heat. The sun represents the eye of the Lord and traverses its orbit in obedience to His order.”
The sun is the king of the planets, and the sun-god (at present of the name Vivasvān) rules the sun planet, which is controlling all other planets by supplying heat and light. He is rotating under the order of Kṛṣṇa, and Lord Kṛṣṇa originally made Vivasvān His first disciple to understand the science of  Bhagavad-gītā . The  Gītā  is not, therefore, a speculative treatise
