An unsatisfied brāhmaṇa wanders restlessly from one planet to another, even if he becomes King of heaven. But a satisfied brāhmaṇa, though he may possess nothing, rests peacefully, all his limbs free of distress. KB 10.52.32 “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.
