So this is position. Therefore, because we are Kṛṣṇa conscious, we are servants of God, therefore it is our duty to save this human civilization. You see. Kṛṣṇa wants it. And to save this human civilization, these two classes are required very urgently. So you American boys and girls, you are intelligent, you have got all facilities. At least in your country, create these two classes, brāhmaṇa and kṣatriya. The world will be saved, and you will be saved, and Kṛṣṇa will be pleased. Brāhmaṇa's business means that people should know what is God, what is our relationship with Him. That is brāhmaṇa's... And kṣatriya's business is to give protection to the people so that may all know what is God. That is kṣatriya's... And vaiśyas business is to provide food for them, production. And śūdras is to help all these three classes by their labor. This is social organization. It is not that everyone will become brāhmaṇa or everyone will become kṣat... No. At the present moment, the Communists are trying: "Everyone should be Communist." That is not possible. You cannot make everyone of the same class. No. That is not possible. You have to use your intelligence in such a way that these four divisions can work cooperatively and become perfect.
And that is suggested here, svanuṣṭhitasya dharmasya saṁsiddhir hari-toṣaṇam (SB 1.2.13). That common platform means how to please Kṛṣṇa. Never mind you are brāhmaṇa, you are kṣatriya, you are vaiśya. But so long we are in the material world, there must be four divisions. The kṣatriyas should give protection; otherwise the demons will disturb. So there is the necessity of war with the demons, for kṣatriya. So these three classes are required, brāhmaṇa, kṣatriya, to give protection. And as soon as the social system is organized, the perfectional point is to satisfy Kṛṣṇa, or the Supreme Lord.
