The Vedānta says, janmādy asya yataḥ (SB 1.1.1). Everything, whatever we see, it has got a source of generation, and that is Brahman, Absolute Truth. So these guṇas, these material guṇas, they are also generated from the Absolute Truth. That is explained in Bhagavad-gītā also. But here everything is perverted reflection. Therefore we see in a different way it is represented.
Guṇa-nāma-kriyā-rūpair vibhāvyante yathā-tatham. And those qualities, guṇa-nāma, guṇa-nāma-kriyā-rūpaiḥ, when the qualities begin to act, they are represented in different varieties, these qualities. These qualities of goodness, passion and ignorance, when they are interacted, they represent in different varieties of representation. Just like when there is quality of goodness, then it is brāhmaṇism. That is the representation of the quality of goodness.
And when the quality of passion is represented, that is the quality of kṣatriya. And when the quality of ignorance is represented, that is the presentation of the śūdras. And mixed-up quality of ignorance and passion, that is vaiśya. Cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13). That is stated in the Bhagavad-gītā that, "These four qualitative representation, Brahmin, kṣatriya . . ."
So when it is creation by the Supreme Lord, it is not that the Brahmins are to be found only in India. That is another wrong conclusion. Because Brahmins means representation of the quality of goodness. Anywhere you find the quality of goodness, that is brāhmaṇism.
