Madhudviṣa: Purport. "Herein we find the history of the Bhagavad-gītā traced from a remote time when it was delivered to the kings or all planets. The royal order is especially dedicated to the protection of the inhabitants, and as such, its members could also understand the science of the Bhagavad-gītā in order to rule the citizens and to protect them from the onslaught of material bondage to lust. Human life is meant for the 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 people may take advantage of this great science and pursue a successful path, utilizing the opportunity of the human form of life."
Prabhupāda: Yes. In the Bhagavad-gītā it is stated... (babies making noises) Oh, you should remove, yes.
Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). This knowledge, this transcendental knowledge, was imparted formerly to the kings because the kings were very responsible for the welfare of the citizens. When the kings were not responsible, then gradually the government by the people was introduced. Otherwise, formerly, the kings were very responsible, especially for the advancement of transcendental knowledge of the citizens. Evaṁ paramparā-prāptam imaṁ rājarṣayaḥ. Rājarṣayaḥ means "the sages among the kings." Although they were in royal order, they were very saintly persons. There are many examples, just like Mahārāja Yudhiṣṭhira, Mahārāja Parīkṣit. They were emperor of the world, but still, so pious, so religious, and so advanced in transcendent knowledge that there is no comparison. So especially meant that this was taught to the kings, to the royal order who were very pious and advanced in spiritual knowledge. Go on.
Madhudviṣa: "This supreme science was thus received through the chain of disciplic succession and the saintly kings understood it in that. But in the course of time the succession was broken, and therefore the science as it is appears to be lost."
Three: "That very ancient science of the relationship with the Supreme is today told by Me to you. Because you are My devotee as well as My friend, therefore you can understand the transcendental mystery of this science."
Purport: "There are two classes of men, namely the devotee and the demon. The Lord accepted Arjuna as the recipient of this great science owing to his being a devotee of the Lord. But for the demons it is not possible to understand this great, mysterious science. There are a number of editions of this great book of knowledge and some of them are commented upon by the devotees, and some of them are commented upon by the demons. Commentary by the devotees is real, whereas that of the demons is useless."
Prabhupāda: Because it is said here that "that very ancient science of the relationship with the Supreme is today told by Me to you because you are My devotee," so this transcendental science cannot be understood simply by academic education. It is not possible. There is a secret. Just like in the ordinary educational field, nobody is allowed to study law unless he is a graduate of the degree college. At least in India that is the law. Nobody can be admitted in the law college unless he is a graduate because he will not be able to understand.
Similarly, in the Vedas it is also said, "Unless one has acquired brahminical qualifications, he should not study Vedas." So in every department, if you want to take education in a particular line, you have to qualify yourself to enter that school or college. Similarly, if you want to study Bhagavad-gītā, then you have to become a devotee. Simply academic educational qualification will not help you, because it was spoken to the devotee.
Kṛṣṇa says that "That very ancient science of relationship with the Supreme is today told by Me to you because you are My devotee." So how the nondevotees can understand? Nondevotee cannot understand. And who is a devotee? And who is a nondevotee? Devotee means one who accepts the supremacy of the Supreme Lord, and he is convinced, his eternal relationship with God.
Just like Lord Jesus Christ. He was threatened with death punishment. He was crucified. Still, he was convinced, his relationship with God. Here is a devotee, example of devotee. Devotee means he is firmly convinced about his relationship with God. And what is that relationship? That relationship is on the basis of love. The devotee loves God, and God loves devotee. This is the only relationship. That's all. God is after devotee, and devotee after God. This is relationship.
