There is always a difference of opinion between a smarta-brahmana and a Vaisnava gosvami. There are even smarta opinions and Vaisnava gosvami opinions available in astrological and astronomical calculations. By calling Nityananda Prabhu a bhrasta avadhuta (a rejected paramahamsa), Advaita Acarya Prabhu in a sense accepted Nityananda Prabhu as a paramahamsa. In other words, Nityananda Prabhu had nothing to do with the rules governing smarta-brahmanas. Thus under pretense of condemning Him, Advaita Acarya was actually praising Him. In the avadhuta stage, the paramahamsa stage, which is the supermost stage, one may appear to be visayi, on the platform of sense gratification, but in actuality he has nothing to do with sense gratification. At that stage, a person sometimes accepts the symptoms and dress of a sannyasi and sometimes does not. Sometimes he dresses like a householder. We should know, however, that these are all joking words between Advaita Acarya and Nityananda Prabhu. They are not to be taken as insults.
