why did babuli go to his native village?

Because there is going to be a partition in the house between the brothers. It was due to the second elder brother

he got a letter frm his elder brodr which ws abt the partition of their ancester's property and his brodr called him to take his share. aftr reading tht letter he felt ashamed tht he didint evn thought abt his family and obeyed his broder's request and his wife ws also interested to get to knw abt their share .Therefore he went there.

He went there for the final break up of "the domestic body" that was to take place. After recieving a letter from his elder brother, at first sight of the letter, babuli's heart just missed a beat out of anxiety but when he read the letter, he felt ashamed at his ingratitude. He didn't even think of his family once in the pretext of being busy in the city life. The city life made him engrossed in his own work so much that he didn't even care the least for his family. Moreover, when he broke out this deadly news in front of his wife, then he saw her unpurturbed. He felt that all those vows of marriage were fake b'coz his wife promised to be a binding factor in the family.
