on this day , elders in the house narrate the story of satyavan and savitri.
in olden days there ruled a king called asrapathi . he had no children. he performed savitri yagya and was blessed with a baby girl who was named savitri. when she attained the marriageable age , her parents looked for a suitable match. but could not find any. so they told her to look for a groom herself. so she went on to look out and went into jungle. there raja dyumatsen ,who was cheated by his enemies,was living with his queen and son satyavan in a hut. satyavan was an obedient son and devoted towards his parents. so savitri was impressed and decided to marry him. she came home and told her parents about this. that time naradh muni came there, he heard this and said, it is a good decision, but dyumatsen is destined to die in one year from now. savitri's father told her to look for another groom.but she was adamant. so her father went to the jungle to talk to raja dyumatsen who was very happy at the same time worried how savithri will be able to lead this hard life in the jungle. but her father persuaded and they both got married and went to jungle. they lived happily.but savitri remembered narada's word always. so she did fast and pooja's regularly.she offered neivedyam made of kaarai rice and toor dal that is why this is called karadai nombu.
that day when satyavan went to cut the wood she went with him with the permission of her in-laws.while cutting he felt giddy and got headache . he stopped the work and rested on savitri's lap. that time yama came and took his soul and went.
When savitri saw Yama taking her husband's soul , she followed him.he asked her to go back home. but she followed him pleading him to leave satyavan and talking with him regarding dharma .yama was pleased and told her satyavan's life is over he cannot return him instead he can give her 3 boons. first she asked that her father in law should get back the kingdom next his eye sight should come back .last she requested for a son for her father. yama granted the wishes.
again she started following him persuading him to return satyavan. yama told her not to follow him and return home. but she did not listen , so yama blessed her with one more boon.but not to ask satyavan. savitri said she would like to have children. yama granted.suddenly he realised savitri's cleaverness. he appreciated her determination to marry the man she loved knowing that she can live with him for only one year. so her dedication saved her husband. he returned satyavan. she came back to the place where satyavan was lying .she woke him up and went back home happily. she saw her father in law got back his eye sight and kingdom. she told them what all happened and they lived happily.
