Caitanya-caritāmṛta 11.192
Blended reading (Sanskrit + English inline)
The word Āryan means advanced. Unless one is spiritually advanced, he cannot be called an Āryan, and this is the difference between Āryan and non-Āryan. Non-Āryans are those who are not spiritually advanced. By following the Vedic culture, by performing great sacrifices and by becoming a strict follower of the Vedic instructions, one may become a brāhmaṇa, a sannyāsī or an Āryan. It is not possible to become a brāhmaṇa, sannyāsī or Āryan without being properly qualified. Bhāgavata-dharma never allows one to become a cheap brāhmaṇa, sannyāsī or Āryan. The qualities or qualifications described herein are quoted from Śrīmad-Bhāgavatam (3.33.7) and were spoken by Devahūti, the mother of Kapiladeva, when she understood the influence of devotional service (bhakti-yoga). In this way Devahūti praised the devotee, pointing out his greatness in all respects.
