It is the duty of the government, the government officers, the head of the government, they should learn Bhagavad-gītā. Here it is said, evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). The rājas, the kings, the government, they understood. Therefore the kingdom was so peaceful, without any care for the citizens. The citizens were also trained up very nicely—brāhmaṇa, kṣatriya, vaiśya, śūdra. Everyone is employed. It is the duty of the government to see that everyone is engaged. Otherwise, idle brain will manufacture devil's brain. They will manufacture so many things, and there will be chaos. In every country nowadays, all over the world, there are so much unemployment. Why there . . . why one should be unemployed? He must be trained up in such a way that he's employed, he's engaged. This is the duty. So if you understand Bhagavad-gītā, then you'll be able to train your students, your citizens, your subordinates, how to remain engaged. Just like in our Kṛṣṇa consciousness Society, we are simply after the people whether he is engaged or not. There must be engagement. If one remains idle, then it will be devil's workshop. Immediately māyā will dictate, "Do this, do this nonsense, do that nonsense, do that nonsense."
So it is the duty of the brāhmaṇa, it is the duty of the father, it is the duty of the public leader, it is the duty of the government to see that everyone is engaged, everyone is employed. As a brāhmaṇa, he must be engaged in studying Vedic literature for instructing others. That is brāhmaṇa's business. And kṣatriya's business is to give protection. Just like Kṛṣṇa was playing as a kṣatriya in Dvārakā. As soon as there is some attack, immediately whole family goes to fight—Kṛṣṇa, Balarāma, Pradyumna. You have seen in the Bhāgavata. Kṣatriya's business is to give protection, and vaiśya's business is to give protection to the cows. As kṣatriya's business is to give protection to the citizens, human being, similarly, vaiśya's business is to give protection to the cows—not to send them to the slaughterhouse—to see the cows are very well fed, they are fatty, strong, that they must be given food, sufficient food.
So because they do not read Bhagavad-gītā, they do not know how to maintain the whole society; therefore there is now chaos. Therefore it is needed, imaṁ rājarṣayo viduḥ. The rāja, the kings, the government or the government men must study Bhagavad-gītā. Then it will be nice. Imaṁ rāja . . . and ṛṣayaḥ. Ṛṣayaḥ will give you . . . Ṛṣayaḥ means great saintly persons, the brāhmaṇas. They should give to the government men . . . but who is consulting the saintly person? Just like we are trying to preach this Bhagavad-gītā. We are trying to give the essence of knowledge. Satataṁ kīrtayanto māṁ yatantaś ca dṛḍha-vratāḥ (BG 9.14). Mahātmā. The symptoms of mahātmā is that he is always engaged in chanting the glories of the Lord. Satataṁ kīrtayanto mām. The Bhagavad-gītā says that catur-vidhā bhajante mām: "Four classes of men comes to worship Me." Bhajana means sevā. Sevā. So sevā means bhakti. Śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam, arcanaṁ vandanam . . . (SB 7.5.23). These are the sevā formula. So the devotees are engaged in sevā, in service of the Lord.
