Vaishnava traditions say that one chola king tried to kill ramanuja acharya.He escaped to karnataka.Then the king imprisoned kurathalwan and periyavachan pillai,ramanuja's disciples.
King asked them to sign a olai chuvadi.It said "shivam is greatest".They signed it as "Shivam is greatest than pathak"(shivam also means 3/4 of a litre and pathak is 0.5 litre--I am not sure) Angry king asked to blind their eyes.Kurathalwan plucked his eyes and threw it in front of king.Periyavachan pillay's eyes were blinded by tying camphor to his eyes.
Which chola king was it?It was in end of 12th century(1190-1210)That king is referred as "kirumi kanda cholan".Was that kulothunga 1 ,the great or his son?
