Fifty years out of one hundred years, fifty years wasted by sleeping. And then balance fifty years, twenty years in childhood and youthhood, sporting, playing; another twenty years in old age . . . Jarayā grasta. Janma-mṛtyu-jarā-vyādhi (BG 13.9). These are inevitable. As birth is inevitable, death is inevitable, similarly, old age is inevitable. So in this way our time is wasted, because we do not know how valuable this human form of life is. There is no such education. They think human life is as cheap as dog's life, but factually it is not. Bahūnāṁ janmanām ante (BG 7.19). One gets this human form of life, 8,400,000 species of life, especially advanced life, the Āryan civilization . . . Āryan means advanced, advanced in spiritual knowledge. The materialists, they claim Āryan only from the bodily conception, but that is not the fact. Anyone who is advanced in spiritual life, they are called Āryans. Anārya-juṣṭam (BG 2.2). Arjuna was chastised by Kṛṣṇa that "You are talking like non-Āryan." Anārya-juṣṭam.
So non-Āryan and Āryan, what is the difference? The Āryan civilization means this varṇāśrama-dharma—four varṇas, four āśramas. And non-Āryan means there is no division. Everyone is one or equal. That is advocated now at the present moment. In India also, they think of casteless society, no caste. But it is not caste. It is division of culture. Brāhmaṇa means advanced in culture; kṣatriya means less advanced than the brāhmaṇa; and vaiśya means less advanced; and śūdra is less advanced; and the pañcamas, fifth grade, sixth grade, kirāta-hūṇāndhra-pulinda-pulkaśā ābhīra-śumbhā yavanāḥ khasādayaḥ (SB 2.4.18), they are less. In this way, high grade and low grade division of the society. One who follows the high-grade culture, they are called Āryans, ārya. In many places in Vedic literature the superior person is addressed as ārya.
