Kṛṣṇa, when found Arjuna, that he was in the battlefield and Kṛṣṇa Himself is guiding him and becoming the chariot driver, and He saw that "Arjuna is declining fight?" He became surprised. So He chastised him, kutas te kaśmalam idaṁ viṣame samupasthitam anārya-juṣṭam (BG 2.2). Āryan, ārya, ārya. "So this is not for a gentleman, business. You are behaving like non-Āryans." Non-Āryan. So this is the difference between culture and nonculture, that . . . There is a Bengali proverb that one girl was to dance on the stage. So in Indian civilization the girls or the woman, they cover their head with, from superiors. So nachte boshe ghumtano. She has gone to dance on the stage, and she is pulling on the veil. "Now, where is the opportunity of here to become a household wife? You have come to dance." So similarly, Arjuna was chastised, that "You have come to fight, and now you are becoming very nonviolent, atheist . . . er, theist. What is . . .? So this is anārya. You have to do your duty in proper place." That is Āryanism. That is ārya. Ārya-samāj means one who knows his duty, how to do it in proper time. So kṣatriya, his duty is to fight, to defend from the hands of the enemy. So he was declining to fight, so He chastised him, "Non-Āryans. You are not Āryan."
So here Śukadeva Gosvāmī says, "My dear king, if a diseased person eats the pure, uncontaminated food prescribed by a physician, he is gradually cured, and the infection of disease can no longer touch him. Similarly, if one follows the regulative principles of knowledge, he gradually progresses towards liberation from material contamination." This is the translation of the . . . Nāśnataḥ pathyam. Pathyam. Pathyam means good foodstuff, not "Anything I can eat." That is the business of the hogs and dogs. Just like hogs have no discrimination. Anything, up to stool you give him, it will eat. That is not human civilization.
