Harihar kaka path ke aadhar par bataiye ke harihar kaka ke oopar thakurbari ke mahant ka jaadoo kyon chal gaya ki ve thakurbari me rehne ko tatpar ho gaye aur wahi rehne lage ? Unke bhaiyo tatha unki patniyo ke vyavhar ko aap kaha tak oochit mante hai tatha aapke is path se parivaro me rehne waale harihar kaka jaise bujurgo ke saath kese vyavhar ki prerna tatha shiksha milti hai. Urgent answer fast. Please!! 

see what happened in this chapter is that mahant and harihar's brothers both wanted the property i,e 15 bhege khet. mahant ka jaado worked on harihar kaka because he gave him a offer and advised him to donate the land to the temple and in return he will get a lot of facilities and even food for 3 times and a luxurious bed and many things its written in the textbook. 

see for the second question i think that because of the property there family ka behaviour changed a lot. like initially they were carrying for him a lot and then slowly they thought that harihar kaka is a burden for us and as he is not giving the property then why should we take care of him. then after the kidnapping from mahant and party harihar kaka's brother took care of him a lot so that he will be secured and easily give the property to them.

it gaved a very wrong impression about the mahant and harihar kaka's brother
