Lal Kamal and Neel Kamal then went inside a room

Lal Kamal and Neel Kamal then went inside a room and closed the door. They were waiting there quietly. So many night passed but they became restless as nobody came to this room. After a fortnight one day at midnight, after waiting for a long time the princes felt very sleepy. Neel Kamal said fondly to his dear brother Lal Kamal - “brother, I am going to sleep first, next turn  will be yours. Listen carefuly, if any Demon came in the meantime and ask your name, tell my name first, not yours.” Then he went to sleep.
Soon thereafter, in the dark night, somebody knocked at the door, Lal Kamal was ready and alert for that with his naked sword. The group of Demons came there. as they could not see well in the night light, said - ‘put off the light’. Lal Kamal answared ‘No’, never”.
