Pothi parh parh jag mua Pandit bhaya naa koi. ........dhai aakhar PREM KA PARHEY SO PANDIT HOYE. ..."

why did shankara charya did tarka, after every sadhana
kiahan too allowed arjun to ask and get convinced not just accept , even though he was jagadguru
and why at all there is debate is encouaraged , and why readers do not just read blog and forget

because man wants the precise comprehensive grasp with concentrated truth, not just some stray opinions 

that is how toi is with elaborate badge system 
so that participants share as many views of truth as is humanly possible 

every saint has striven his best to give and seen that it is received well by the masses

the idea is we sharpen our abilities to the highest possible level
