Prabhupāda: You have heard something about our Kṛṣṇa consciousness movement?
Dr. Arnold Toynbee: I know something in general, yes. Perhaps you would tell me more.
Prabhupāda: It is based on Bhagavad-gītā.
Dr. Arnold Toynbee: Yes.
Prabhupāda: You have read Bhagavad-gītā, I think.
Dr. Arnold Toynbee: Yes, yes.
Prabhupāda: So primarily, it is based on Bhagavad-gītā, and then it is being explained from Śrīmad-Bhāgavatam.
Dr. Arnold Toynbee: Yes, yes.
Prabhupāda: Bhagavad-gītā is the preliminary study of Śrīmad-Bhāgavatam.
Dr. Arnold Toynbee: Yes, yes, yes.
Prabhupāda: So we get ideas from Bhagavad-gītā how God consciousness can make the human society happy.
Dr. Arnold Toynbee: Yes, yes.
Prabhupāda: The aim of human society should be God realization. That is the distinction between an animal and a human being.
Dr. Arnold Toynbee: Yes.
Prabhupāda: So Bhagavad-gītā recommends that the whole society should be divided into four divisions: the brāhmaṇa, or the most intellectual persons; the kṣatriyas, the administrators; the vaiśyas, the mercantile agriculturists; and the śūdras, ordinary men, laborer or worker. Because this material world is conducted by three modes of nature, goodness, passion and ignorance. So according to the quality of the person, he should be listed in different categories. And it is the duty of the state to see that all these categories, divisions, they are working nicely.
