FIRSTLY he explained to him but BHAKAT Prahalad  no understand the rules of his father , due to this problem HIRANKASYAP decided to kill his son (Prahalad ). and after that he planned to kill ,and he cut the body of BHAKAT PRAHLAD and thrown up in the river. but BHAKAT PRAHALAD escapes . it is the amazing events for HIRANKASYAP AND his public , after that he again try to kill BHAKAT PARAHLAD . BUT again he escapes.                                                                                                                                                                         after that he decided to kill in front of the eye, and he ready to her sister ,which name is HOLIKA . HOLIKA had a soul ,which cannot be burn , then HOLIKA wear the soul and sit in the cheetah (fire) but at the moment a terrible storm came and the soul wrapped up in the body of BHAKAT PARAHLAD ,AND HOLIKA burns by the fire of cheetah . and now this day celebrate in INDIA by name of HOLIKA DAHAN. THIS FESTIVAL'S main motto is destroy the evil and  say support to truth .                                                                                                                                                                             after few days RAJA HIRANKASYAP dies by the GOD VISHNU in the evening by the form of BARASINGHA , who was neither man ,neither woman and neither animal , who was in combo form of man , woman ,and animal , by the way of this a evil person killed by the GOD and the truth are also alive in the earth for humanity and calm.   THANKS.
