During the days of Swamy Parasarabhattar , a vedantin came to have darshan of Lord Ranganatha . He was very learned in sastras .
While having darshan he noticed Swamy Parasara bhattar advising a group of devotees .The Vedantin walked near to Swamy and asked him to explain how a vaishnava is distinquished from a smarta . Swamy Parasara bhattar did not care to enter into an elaborate controversy with the adversary on this query , delicate in as much as it is a bone of contention between the two divisions the advaitins and visishitadvaitins.
He just smiled and called his attention to the signs of chakra and shankha inscribed in both his arms a sacrament enjoyed by sastras on all vaishnavas .
The vedantin said ..Oh I see !! but what authorities can you quote from the shastras justifying you to set this type of custom ? of wearing Urdhva pundra and the sacraments.
Swamy Parasara bhattar replied .. I shall not trouble you with all that , for when I shall quote one authority , to which we commonly agree . The first sutra of Apastamba Dharma which says Wise practices of our wise elders are our best authority . Only after this comes Vedas .. Adiyens father Kooresa observed the sacrament in question and therefore , Adiyen does it .. Hope you to follow your Elders footsteps without doubt ..
The vedantin was silenced ..Though he was elder to Swamy Parasara bhattar , he offered obeisances and moved away quickly…..
