Lord Kṛṣṇa continued: "O best of all the brāhmaṇas, you should always remain satisfied, for if a brāhmaṇa is always self-satisfied he will not deviate from his prescribed duties; and simply by sticking to one's prescribed duties, everyone, especially a brāhmaṇa, can attain the highest perfection of all desires. Even if a person is as opulent as the King of heaven, Indra, if he is not satisfied he inevitably has to transmigrate from one planet to another. Such a person can never be happy under any circumstances; but if one's mind is satisfied, even if he is bereft of all possessions, he can be happy living anywhere."
This instruction by Kṛṣṇa to the brāhmaṇa is very significant. The purport is that a true brāhmaṇa should not be disturbed in any situation. In this modern age, Kali-yuga, the so-called brāhmaṇas have accepted the abominable position of śūdras or less and still want to pass as qualified brāhmaṇas. Actually, a qualified brāhmaṇa always sticks to his own duties and never accepts those of a śūdra or of one less than a śūdra. It is advised in the authorized scriptures that a brāhmaṇa may, under awkward circumstances, accept the profession of a kṣatriya or even a vaiśya, but never is he to accept the profession of a śūdra. Lord Kṛṣṇa declared that a brāhmaṇa will never be disturbed by any adverse conditions if he scrupulously sticks to his religious principles. In conclusion, Lord Śrī Kṛṣṇa said, "I offer My respectful obeisances to the brāhmaṇas and Vaiṣṇavas, for the brāhmaṇas are always self-satisfied and the Vaiṣṇavas are always engaged in actual welfare activities for human society. They are the best friends of the people in general; they are free from false egoism and are always in a peaceful condition of mind."
Lord Kṛṣṇa then desired to know about the rulers (kṣatriyas) in the brāhmaṇa's kingdom, so He inquired whether the citizens of the kingdom were all happy. A king's qualification is judged by the temperament of the people in the kingdom. If they are happy in all respects, it is to be understood that the king is honest and is executing his duties rightly. Kṛṣṇa said that the king in whose kingdom the citizens are happy is very dear to Him. Of course, Kṛṣṇa could understand that the brāhmaṇa had come with a confidential message; therefore He said, "If you have no objection, I give you liberty to speak about your mission."
