Śrī Caitanya Caritamrta · Text Madhya 11.192
অহো বত শ্বপচোঽতো গরীয়ান্
যজ্জিহ্বাগ্রে বর্ততে নাম তুভ্যম্ ।
তেপুস্তপস্তে জুহুবুঃ সস্নুরার্যা
ব্রহ্মানূচুর্নাম গৃণন্তি যে তে ॥ ১৯২ ॥
aho bata śva-paco ’to garīyān
yaj-jihvāgre vartate nāma tubhyam
tepus tapas te juhuvuḥ sasnur āryā
brahmānūcur nāma gṛṇanti ye te
Śrī Caitanya Mahāprabhu then recited the following verse: “ ‘My dear Lord, one who always keeps Your holy name on his tongue becomes greater than an initiated brāhmaṇa. Although he may be born in a family of dog-eaters and therefore by material calculation may be the lowest among men, he is still glorious. This is the wonderful effect of chanting the holy name of the Lord. It is therefore concluded that one who chants the holy name of the Lord should be understood to have performed all kinds of austerities and great sacrifices mentioned in the Vedas. He has already taken his bath in all the holy places of pilgrimage. He has studied all the Vedas, and he is actually an Āryan.’”
